Trying to create some GUIs in R.
I create a window and it disappears.
What am I missing here?
library(tcltk)
tt <- tktoplevel() <br>
x <- tkbutton(tt, text = "Text") <br>
tkpack(x)
What system do you use? It works just fine on macOS with R 3.4.1
This is strange. It should work fine from command line as well:
I assume that you have XQuartz (https://www.xquartz.org) installed and configured.

I'm doing an R project on RStudio (RStudio 2021.09.1+372 "Ghost Orchid" Release for Windows), (R version 4.1.2).
I'm working on Windows 10 x64.
I want to create an Undirected Graph from a dataset:
library(gRbase)
library(gRim)
library(gRain)
data(BodyFat)
BodyFat <- BodyFat[-c(31,42,48,76,86,96,159,169,175,182,206),]
BodyFat$Age <- sqrt(BodyFat$Age)
BodyFat$Weight <- sqrt(BodyFat$Weight)
names(BodyFat)[names(BodyFat) == 'BodyFat'] <- 'BodyFatPerc'
gRbodyfat <- BodyFat[,2:15]
graph.MyGraph <- cmod(~.^., data = gRbodyfat)
AIC.MyGraph <- gRbase::stepwise(graph.MyGraph)
I'm still exploring RStudio and graphical models, so I run these lines from the console, one by one.
When I run the last line of code, R session aborts and I get the following pop-up message:
I've also tried the following lines of code (I changed the last line):
library(gRbase)
library(gRim)
library(gRain)
data(BodyFat)
BodyFat <- BodyFat[-c(31,42,48,76,86,96,159,169,175,182,206),]
BodyFat$Age <- sqrt(BodyFat$Age)
BodyFat$Weight <- sqrt(BodyFat$Weight)
names(BodyFat)[names(BodyFat) == 'BodyFat'] <- 'BodyFatPerc'
gRbodyfat <- BodyFat[,2:15]
graph.MyGraph <- cmod(~.^., data = gRbodyfat)
AIC.MyGraph <- stepwise(graph.MyGraph)
but I get the same problem. I tried three or four times running those lines of code, R aborted everytime.
My gRbase, gRim, gRain, Rgraphviz and RBGL libraries are in the home folder:
C:/Users/MyUser/Documents/R/win-library/4.1
Any advice?
EDIT:
I've tried uninstalling/reinstalling R, Rtools, RStudio, reinstalling libraries, updating them, I've tried launching RStudio as Administrator, I've tried changing computer.
The last thing I tried is this:
uninstalling R, Rtools and RStudio
deleting .RData and .Renviron files in the Documents folder
deleting all libraries
downloading R (latest version) from CRAN webpage and installing it as Administrator
downloading Rtools (latest version from webpage) and installing it as Administrator
creating the .Renviron file as described here
downloading RStudio (latest version from webpage) and installing it as Administrator
installing BiocManager as described here (when asked to update Matrix library I said NO, I thought it could be the problem)
installing gRbase, gRim, gRain libraries as described here (when asked to update fansi library I said NO because it said "There are binary versions available but the source versions are later", I thought it could be the problem)
Tried again the lines of code
Still got the problem, R session aborted again.
A friend of mine doing a similar project used gRbase::stepwise function, so I inserted his code in the console and the function worked. So I think the problem might be the object of the function, graph.MyGraph. The cmod function works fine, so maybe there's a problem with gRbodyfat, which is used to build graph.MyGraph.
If I run these lines (I tried changing the dataset, I used BodyFat instead of gRbodyfat):
graph.MyGraph <- cmod(~.^., data = BodyFat)
AIC.MyGraph <- gRbase::stepwise(graph.MyGraph)
I get the following error:
Error in dim(res) <- c(NSEL, NSET) :
dims [product 210] do not match the length of object [14]
Don't know what to do.
EDIT:
I've tried debugging gRbase::stepwise function and I get this:
The problem appears to be the iModel function.
EDIT:
I've discovered that if I use graph.MyGraph <- cmod(~.^1, data = gRbodyfat) the gRbase::stepwise function works fine.
I recently updated my MacBook air (2017) to the Mojave OS and proceeded to update my version of R and Rstudio. Unfortunately, ever since the 'plotTangentSpace' command no longer functions appropriately even when attempting to run the example 'plethodon' code from the Geomorph vingette, I always receive the following error in the output (bolded below):
data(plethodon)
Y.gpa<-gpagen(plethodon$land) #GPA-alignment
|====================================================================================| 100%
gp <- interaction(plethodon$species, plethodon$site)
plotTangentSpace(Y.gpa$coords, groups = gp)
Error in plotTangentSpace(Y.gpa$coords, groups = gp) :
unused arguments (Y.gpa$coords, groups = gp)
I have tried uninstalling and reinstalling R for a MacOS many times including versions 4.0.2, 3.6.3, 3.6.1, and 3.2.1. I have also uninstalled and reinstalled XQuartz several times.
If anyone has encountered a similar issue or has any other ideas I can try I would really appreciate the help. Thank you!
If you execute:
?plotTangentSpace
You should see that this is a deprecated function. That means you should not be using it. It says:
Notes for geomorph 3.3.0 and subsequent versions
I suspect you have not updated your copy of the vignette. There are instructions on the help page for an alternate approach. The example in the help page for the suggested function is:
data(plethspecies)
Y.gpa <- gpagen(plethspecies$land) #GPA-alignment
### Traditional PCA
PCA <- gm.prcomp(Y.gpa$coords)
summary(PCA)
plot(PCA, main = "PCA")
For the plethodon data they suggest:
PCA.w.phylo <- gm.prcomp(Y.gpa$coords, phy = plethspecies$phy)
summary(PCA.w.phylo)
plot(PCA.w.phylo, phylo = TRUE, main = "PCA.w.phylo")
So start a new session (to unload the currently loaded geomorph namespace, and execute this at the r session command line:
install.packages("geomorph")
You should be getting version 3.3.1 of the geomorph package.
I think I found the problem! In my case, the error was due to a old version of the package RRPP, which is required by Geomorph. After updating it, Geomorph is working perfectly! Hope this can be useful for you too.
I came across the same error but after updating the RRPP and rgl packages required for geomorph, the gm.prcomp() function worked for me. I hope this helps if you haven't figured it out already.
I have a Encoding Problem in KNIME.
Following code works perfectly in RStudio, the symbol ° is printed out correctly.
library(grid)
library(gridBase)
library(gridExtra)
library(ggplot2)
fn <- "C:/Temp/textR.pdf"
pdf(file=fn)
df <- data.frame("crit °C", 1)
g1 <- tableGrob(format(df, core.just="left"))
grid.arrange(g1, ncol = 1)
dev.off()
I want to use this code in an R Snippet in KNIME, unfortunately it won´t work there, instead of "°" I get "°".
What i already tried:
setting Preferences to UTF-8 in KNIME ->Preferences->General->Workspace
https://tech.knime.org/forum/knime-textprocessing/problems-exporting-utf-8-csv-writer
use ggsave
use Pdf Cairo instead (solution from using Unicode 'dingbat-like' glyphs in R graphics, across devices & platforms, especially PDF) but i am not sure if I had the family package installed...
Can anyone help me? I am using KNIME 3.1.1 and R_3_2_1
It was working well for me (also Windows, in my case Windows 10, 64 bit, English locale, KNIME 3.1.2, R 3.0.3).
You might give a try with the following change:
df <- data.frame("crit \u00B0C", 1)
(\u00B0 stands for the unicode degree sign.)
Using this works in R console:
plot(G)
but when typed into a cell in jupyter I get:
starting httpd help server ... done
and no graph.
So here is what I did.
Into Anaconda 2.7.11, I installed R essentials
conda install -c r r-essentials
started up jupyter
notebook jupyter
installed needed reqs, XML and googleVIS, by typing this into a cell
options(repos=structure(c(CRAN="https://cloud.r-project.org/")))
install.packages('googleVis')
install.packages('XML')
typed this code into a cell
suppressPackageStartupMessages(library(googleVis))
library(googleVis)
library(XML)
url <- "http://en.wikipedia.org/wiki/List_of_countries_by_credit_rating"
x <- readHTMLTable(readLines(url), which=3)
levels(x$Rating) <- substring(levels(x$Rating), 4,
nchar(levels(x$Rating)))
x$Ranking <- x$Rating
levels(x$Ranking) <- nlevels(x$Rating):1
x$Ranking <- as.character(x$Ranking)
x$Rating <- paste(x$Country, x$Rating, sep=": ")
G <- gvisGeoChart(x, "Country", "Ranking", hovervar="Rating",
options=list(gvis.editor="S&P",
projection="kavrayskiy-vii",
colorAxis="{colors:['#91BFDB', '#FC8D59']}"))
then
plot(G)
This code works fine when typed directly into an R console and makes a nice map. But something is causing jupyter to choke on starting a server. I guess since jupyter itself is web page running in a server there is some sort of problem with a web page starting a server?
I have the same issue. According to this demonstration, all you need in an R console is to additionally add this line after loading the library:
library(googleVis)
op <- options(gvis.plot.tag='chart')
The introduction of tag can also be found here in googleVis's documentation. After trying it in Jupyter all I got is a block of .json data and it cannot compile into an interactive graph.
Hope this help in anyway. I will probably try something like plotly, which does work on jupyter.
I'm having trouble getting 'choice' to create output. When the graphical interface launches, I am selecting a partition with the space bar. This creates a black circle around the partition, indicating it has been selected. When I click 'return', nothing happens.
I checked my working directory to look for the output files, but they are not there. I used getwd() to ensure that I have the correct setwd(). No dice.
There was a similar question posted: Exporting result from kml package in R; however, the answer does not work for me.
Any suggestions? I am using R 3.1.0 GUI Mavericks build(6734) and XQuartz 2.7.6. Thanks for any help getting this working.
Here is my code:
setwd("/Users/eightfrench")
mydata <- read.csv("hcris_long3.csv")
cldHCRIS <- clusterLongData(traj=mydata)
kml(cldHCRIS,nbClusters=2:4,nbRedrawing=2,toPlot="both")
X11(type="Xlib")
choice(cldHCRIS, typeGraph= "bmp")
I had the same problem when using RStudio and i solved it just opening the x11 device with no specification. Like this:
setwd("/Users/eightfrench")
mydata <- read.csv("hcris_long3.csv")
cldHCRIS <- clusterLongData(traj=mydata)
kml(cldHCRIS,nbClusters=2:4,nbRedrawing=2,toPlot="both")
X11()
choice(cldHCRIS, typeGraph= "bmp")
Hope this also works for you.
The new version of kml (2.3) fix that, it provide a key to export data with linux as well (not "return" since getGraphicsEvent does not accept "return" using linux, so I have to map another key : 'm')
