what does this error code mean in RStudio - r

I am trying to run dada2 within RStudio. Normally I would run it in Windows. However because I want to run cutadapt as well I have had to create a Linux VM. With some help I now have dada2 and cutadapt installed on my VM. I have copied over my R code which works in RStudio in Windows. I have editted the code on my VM so that it points towards the correct directories, e.g. replaced "c:\Rtemp" with "~/Rtemp". I believe I have done this correctly as RStudio reads in dada2 and then my files just like it does when I start the script in RStudio in Windows. However I then get error messages that I don't get when I run the script in RStudio in windows.
fnFs <- sort(list.files(path, pattern="_R1_001.fastq", full.names = TRUE))
fnRs <- sort(list.files(path, pattern="_R2_001.fastq", full.names = TRUE))
sample.names <- sapply(strsplit(basename(fnFs), "_"), `[`, 1)
plotQualityProfile(fnFs[1:2])
Error in (function (cond) :
error in evaluating the argument 'dirPath' in selecting a method for function 'qa': IncompatibleTypes
message: error in evaluating the argument 'x' in selecting a method for function 'which': error in evaluating the argument 'x' in selecting a method for function 'alphabetFrequency': invalid class “BStringSet” object: undefined class for slot "elementMetadata" ("DataTable_OR_NULL")
There are no "install" errors so I don't think the problem is missing installs. Is this error message indicating a problem with the amount of memory on my VM?

I recently ran into this problem while working through the dada2 tutorial.
I fixed it by loading up library(Biostrings) before loading dada2. I was under the impression that dada2 automatically loaded up Biostrings, but this was the fix. Hopefully it works for you.

runjags trouble locating JAGS - error "'where' not found" even after setting jagspath

Seems that runjags suddenly (after update to version 2.0.3-2) has trouble finding JAGS binary, issuing an error:
[1] "Error in system(\"where jags\", intern = TRUE) : 'where' not found\n"
attr(,"class")
[1] "try-error"
attr(,"condition")
<simpleError in system("where jags", intern = TRUE): 'where' not found
I fixed this by putting this line to my Rprofile:
.runjags.options <- list(jagspath = "c:/Program Files/JAGS/JAGS-4.2.0/i386/bin/jags-terminal.exe")
This pretty much fixes the problem (although it is not ideal - previous versions of runjags could find the binary automatically).
However, when the Rgui (in Windows XP) is launched by opening an .Rdata file, which is associated to it, it stops working:
> .runjags.options # it was set in the Rprofile
$jagspath
[1] "c:/Program Files/JAGS/JAGS-4.2.0/i386/bin/jags-terminal.exe"
> require(runjags)
Loading required package: runjags
Warning message:
package ‘runjags’ was built under R version 3.1.3
> runjags.getOption("jagspath")
[1] "Error in system(\"where jags\", intern = TRUE) : 'where' not found\n"
attr(,"class")
[1] "try-error"
attr(,"condition")
<simpleError in system("where jags", intern = TRUE): 'where' not found
Is this a bug? How to fix this?
I am currently calling runjags.options(jagspath = "c:/Program Files/JAGS/JAGS-4.2.0/i386/bin/jags-terminal.exe") in my source after require(runjags), but I would like to avoid this as much as possible!
The problem is in the findjags() function, more specifically use of the 'where' system command which was added to Windows in 2003 and therefore doesn't exist in Windows XP. There is some code in findjags() that is designed to detect earlier versions of Windows and revert to a different method of finding JAGS, but this hasn't changed since version 1.x so I don't know why this has 'suddenly' stopped working. Perhaps there has been a change in your system, or a change in the way the system() command works in R. I have modified this code to work around where I think the error is coming from, but I don't have access to Windows XP (I'm rather surprised that you do!) so I can't test it. I don't think it will do any harm though so I will include it in the next release anyway, after testing on more recent versions of Windows.
I also don't know exactly why the .runjags.options is not being found when you open a .Rdata file, but it is possible that opening a .Rdata file loads the library before setting objects. I will look into this but it is likely not something I can do anything about. The alternative to using runjags.options() is to set the jags argument in calls to run.jags etc.

R package 'biomod2' cannot find file when executing plot function

I am attempting to use the plot() function in the biomod2 package, following a vignette here (http://finzi.psych.upenn.edu/usr/share/doc/library/biomod2/doc/Simple_species_modelling.pdf). Below is the error I am getting:
getwd()
# [1] "/home/gjanzen/Documents/Hufford/Drought/Data/Layers"
plot(myBiomodData)
Error in getExportedValue(pkg, name) : cannot open file
'~/R/x86_64-pc-linux-gnu-library/3.3/viridisLite/data/Rdata.rdb': No
such file or directory In addition: Warning message: In
getExportedValue(pkg, name) : restarting interrupted promise
evaluation
I have confirmed that the Rdata.rdb exists, in the following directory:
f <- file.choose()
f
# [1] "/home/gjanzen/R/x86_64-pc-linux-gnu-library/3.3/viridisLite/data/Rdata.rdb"
So, to me, it looks like the plot() function is looking in the wrong place. How can I change where this function looks for Rdata.rdb? Can I alter the path somehow? Or would changing my working directory fix this?
PS - This is my first post on Stack Overflow, so please forgive any mistakes in etiquette, and/or feel free to point them out to me so that I do not repeat them.
I think that the first thing to try is to reinstall the package viridisLite that seems to be the one that is causing troubles.
install.packages('viridisLite', dep = TRUE)
If this not solves the issue you should try to open a new plotting device threw x11() to check if the issue is not coming from the R (resp. RStudio) plotting device itself.

Error: 'MonetDBLite' is not an exported object from 'namespace:MonetDBLite'

Working through a download script for CPS data found here. Using the script verbatim, per recent update, except for the Java modification that I added for my environment (below) to fix a previous error in loadnamespace. While I am familiar with the basics of R, this is my first foray into MonetDBLite.
# configure Java
if (Sys.getenv("JAVA_HOME")!="")
Sys.setenv(JAVA_HOME="")
library(rJava)
Now I am getting the following error, which generally comes after 380,000 of the 400,000 cps asec lines are processed.
Warning message:

MonetDBLite has just been updated on CRAN, please reinstall.

TreeTagger in R

I have downloaded TreeTaggerv3.2 for Windows and have configured it per the install.txt. I am trying to use it in R with koRpus package. I have set the kRp.env as -
set.kRp.env(TT.cmd="C:\\TreeTagger\\bin\\tag-english.bat", lang="en",
preset="en", treetagger="manual", format="file",
TT.tknz=TRUE, encoding="UTF-8" )
.My data to be tagged is in a file and trying to use it as treetag("myfile.txt") but it is throwing the error-
Error in matrix(unlist(strsplit(tagged.text, "\t")), ncol = 3, byrow = TRUE, :
'data' must be of a vector type, was 'NULL'
In addition: Warning message:
running command 'C:\windows\system32\cmd.exe /c C:\TreeTagger\bin\tag-english.bat
C:\Users\vivsingh\Desktop\NLP\tree_tag_ex.txt' had status 255
The standalone TreeTagger is working on by windows.Any idea on how it works?
I had the exact same error and warning while trying lemmatization on R word vector following Bernhard Learns blog using windows 7 and R 3.4.1 (x64). The issue was also appearing using textstem package but TreeTagger was running properly in cmd window.
I mixed several answers I found on this post and here is my steps and code running properly:
get into R win_library (~\Documents\R\win-library\3.4\rJava\jri\x64\jri.dll) and copy jri.dll (thanks kravi!) to replace it the parent folder.
close and restart R
library(koRpus)
set.kRp.env(TT.cmd="C:\\TreeTagger\\bin\\tag-english.bat", lang="en", preset="en", treetagger="manual", format="file", TT.tknz=TRUE, encoding="UTF-8")
lemma_tagged <- treetag(lemma_unique$word_clean, treetagger="manual", format="obj", TT.tknz=FALSE , lang="en", TT.options=list(path="c:/TreeTagger", preset="en"))
lemma_tagged_tbl <- tbl_df(lemma_tagged#TT.res)
Hope it helps.
I am posting this answer to keep a record. I also faced the same issue due to incorrect specification of the location of jri.dll on 64-Bit processor and windows 8.1. If we call
set.kRp.env(TT.cmd="manual", lang="en", TT.options=list(path="/path/to/tree-tagger-windows-x.x/TreeTagger", preset="en")) and we follow either of following two steps, we can resolve this error:
While installing R, if we install only 64 Bit version of R, and
specify the proper path for these variables
LD_LIBRARY_PATH = /path/to/rJava/jri
JAVA_HOME = /path/to/jdk1.x.x
java.library.path = /path/to/rJava/jri/jri.dll
CLASSPATH = /path/to/rJava/jri
If we already installed both versions viz. 32 bit and 64 bit of R on your computer then just copy jri.dll from /path/to/rJava/jri/x64/jri.dll and replace at path/to/rJava/jri/jri.dll. Further, we need to set the path of above mentioned four variables.
I've got this issue (very similar I guess) and posted query to GitHub.
https://github.com/unDocUMeantIt/koRpus/issues/7
The current working solution for me for this case was easier than I could expect, just downgrading the koRpus package. This can change with time but this version should remain appropriate.
library("devtools")
install_github("unDocUMeantIt/koRpus", ref="0.06-5")
This package is not Java related they said.
You can face the same error while setting up the korpus environment and getting the result from treetagger. For example, when you use:
tagged.text <- treetag(
"C:/temp/sample_text.txt",
treetagger = "manual",
lang = "en",
TT.options = list(
path = "c:/Treetagger",
preset = "en"
),
doc_id = "sample"
)
You would receive a similar error
Error: Awww, this should not happen: TreeTagger didn't return any useful data.
This can happen if the local TreeTagger setup is incomplete or different from what presets expected.
You should re-run your command with the option 'debug=TRUE'. That will print all relevant configuration.
Look for a line starting with 'sys.tt.call:' and try to execute the full command following it in a command line terminal. Do not close this R session in the meantime, as 'debug=TRUE' will keep temporary files that might be needed.
If running the command after 'sys.tt.call:' does fail, you'll need to fix the TreeTagger setup.
If it does not fail but produce a table with proper results, please contact the author!
Here you need to change the value of treetagger, from
treetagger = "manual"
to
treetagger = "kRp.env"
However, before that remember to set the kRp.env as #Xochitl C. suggested in their answer
set.kRp.env(TT.cmd="C:\\TreeTagger\\bin\\tag-english.bat", lang="en", preset="en", treetagger="manual", format="file", TT.tknz=TRUE, encoding="UTF-8")
Once you do this, you'll get the desired result.

Problems building an R package (NAs introduced by coercion)

I have written the Boggler package which includes a Play.Boggle() function that calls, on line 87, a progress bar script using shell:
shell(cmd = sprintf('Rscript.exe R/progress_bar.R "%i"', time.limit + 1), wait=FALSE)
Everything works fine when sourcing the files individually and then calling the main Play.Boggle() function, but when I try to check/build the package (under Win7-64 using RStudio), I get a failure message -- here's what the 00install.out reports:
** preparing package for lazy loading
Warning in eval(expr, envir, enclos) : NAs introduced by coercion
Error in time.limit:0 : NA/NaN argument
To make sure the argument "%i" (time.limit + 1) was correctly passed to the progress_bar.R, I added a cat(time.limit) to the script (commenting the rest out to make sure the package would build without any errors) and directed its output to a log file like this:
'Rscript.exe R/progress_bar.R "%i" > out.log'
Conclusion: the time limit is indeed passed along as expected. So I can't figure out why I get this "NA/NaN argument" error message. It must have something to do with lazy loading, concept that I haven't fully got my head around yet.
So my question is: what can I do to successfully check/build this package with full functionality (including progress_bar.R)?
Note: On github, the progress_bar.R script is there but all its content is commented out so that the package can successfully be installed. The shell(...) function call is still active, doing nothing but executing an empty script.
So the problem arises when trying to build or check, in which case all R scripts are executed, as pointed out by Roland. A simple workaround allows the package to check/build without any problems. The fix is just to add to the progress_bar.R the following lines after it tries to recuperate the commandargs (lines 10-11):
if(time.limit %in% c(NA, NaN))
time.limit <- 10 # or any minimal number
There's surely other ways to go about this. But this being a game programmed for fun, I'll happily go with that patch. Hopefully this can be of help to someone down the road and I won't have wasted 50 precious rep points in vain for that bounty! :D
