I am new to R. I encountered an error when I wanted to use the auto.arima function. The message was:
could not find function "auto.arima"
I've installed the forecast package. I'm using R2.14.1 version and forecast 3.16 in windows 7 operating system. What can I do?
If I could use the auto.arima function in R and get the best result model, I want to call the auto.arima method in my Java project. How would I use the R library in java project?
As the others pointed out: You have downloaded the package with install.packages() or from the menu but you did not load the package. This is done by library(forecast) or require(forecast). You can obtain single functions as well with the command: package::function() just like: forecast::auto.arima(). So much for a little clarification. If you need a graphical user interface (it makes life easier) check out Rstudio Rstudio or R commander install.packages(Rcmdr) or rJava proposed by Zach.
As #Jeromy Anglim says: library(forecast)
http://www.rforge.net/rJava/
When installing, make sure you mark the "Install Dependencies" option.
To use the auto.arima package, you need to install the package "quadprog". Install that package first and put forecast into library and you should be ok
You need to do the following steps
install.packages("xts")
install.packages("forecast", dependencies = TRUE)
library(forecast)
This worked for me.

I am trying to run through a mixed stock analysis in RStudio based on the walkthrough provided by Bolker (https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=043730a02b148396ebd54b2f62e8f6364714b1b2), using the 'mixstock' package and the example 'lahanas98raw' dataset within. However, I am receiving a warning that the 'calc.RL.0' function cannot be found whilst trying to carry out Raftery and Lewis convergence diagnostics (p.14 of Bolker's walkthrough). I am wondering whether one of the packages has not installed properly (i.e., either 'mixstock' or 'coda'), or whether there is another package I can use to run this diagnostic instead.
When I initially tried to install the 'mixstock' package, the following warning came up:
'Warning in install.packages : package ‘mixstock’ is not available for this version of R.'
I tried installing the version of R (2.14.1) described as the 'current version of R' on page 2 of Bolker's walkthrough, but when I then tried to switch to this version of R in RStudio via the options menu, it says that this version of R is not compatible with RStudio. To work around this, I downloaded the 'mixstock' package (version 0.9.5.1) from the CRAN archive (https://cran.r-project.org/src/contrib/Archive/mixstock/) and uploaded it to RStudio this way instead.
This seemed to have worked, as I successfully ran through a significant amount of the code, but a new error arose when I tried to run Raftery and Lewis convergence diagnostics (p.14). When I try to run calc.RL.0(mydata), I receive the following error:
'Error in calc.RL.0(mydata) : could not find function "calc.RL.0"'
However, when I click on 'mixstock' in the package window, everything seems fine and the 'calc.RL.0' function appears, alongside several other 'calc' functions (e.g. 'calc.GR', 'calc.mult.GR', 'calc.mult.RL') that can all be found and run fine. The 'calc.RL.0' function relies on the 'raftery.diag' function within the 'coda' package, so I have also made sure that is installed and called. I have tried a bunch of other methods but nothing seems to be working.
Here is some of my code leading up to the warning message:
## Calculate confidence intervals - i.e., bootstrapping - and plot them
mydata.umlboot = genboot(mydata,"uml")
confint(mydata.umlboot)
plot(mydata.umlboot, ylim=c(0,1))
## Carry out Markov Chain Monte Carlo (MCMC) estimations and plot them
mydata.mcmc = tmcmc(mydata)
mydata.mcmc
confint(mydata.mcmc)
plot(mydata.mcmc, ylim=c(0,1))
## Check that the Markov chains have converged = run Raftery and Lewis diagnostics
library(mixstock)
library(coda)
calc.RL.0(mydata)
'Error in calc.RL.0(mydata) : could not find function "calc.RL.0"'
Could this be something to do with the way the 'mixstock' package was initially installed, or is it likely to be another issue? Is there another way to run Raftery and Lewis diagnostics and still get the outputs I need (diagnostics for the last chain evaluated; the history of how long each suggested chain was)? Any help would be much appreciated - thanks in advance!
The most reliable way to install mixstock, if you have development tools installed on your computer (compilers etc.), is remotes::install_github("bbolker/mixstock") (I don't think I've changed anything/fixed any bugs since the archived version, but if I did the changes would be reflected on GitHub.)
It looks like I forgot to export that function, so
mixstock:::calc.RL.0(mydata)
should work (this is something I can/should fix). Note that the Gelman-Rubin diagnostic (calc.GR(), which is properly exported) is more reliable than Raftery-Lewis anyway ...
I am trying to use the cluster.vcov in R but it keeps telling me
cluster.vcov(regression1, data$country
Error in cluster.vcov(regression1, data$country) : could not find function "cluster.vcov
I have tried installing the package "multiwayvcov" but it says that such package does not exist. Does anybody know how to solve this issue?
Thank you very much,
Max
multiwayvcov package has been deprecated as mentioned here. The author recommends to use the sandwich package now which has the same functionality.
However, I can install both multiwayvcov and sandwich package on my system with R version 4.0.3 using install.packages('multiwayvcov') and install.packages("sandwich").
I am trying to create a character map and was recommended to use Phylotools and Ape packages in R.
I have installed the packages but when I try to do function getStates it comes up with an error message:
x<-getStates(nexdata,"tips")
Error in getStates(nexdata, "tips") : could not find function "getStates"
I have installed the right packages (so I think) and I am quite stuck. Any help would be really appreciated. If you need me to explain anything in more detail let me know.
The function library() loads and attaches add-on packages. You are using phytools and ape, so you should have in your code
library(phytools)
library(ape)
You can read more in the documentation, e.g. at rdocumentation.org/packages/base/versions/3.6.1/topics/library.
I am a beginner in R and I am supposed to make a model thanks to regression beta. I learned that I can use betareg() except that even when installing its package the R does not recognize it and displays me error:
Error: could not find function "betareg"
What could be the cause for that?
The error message you are getting typically arises when calling a function.
Before you can call a function, you have to install the package and load the library.
You can try this:
install.packages("betareg")
library(betareg)
and then call the function with relevant parameters
betareg()
I need to perform an analytic hierarchical process (AHP) on a dataset using R. I have basic understanding of navigation and can follow most guides to perform rudiment analyses. However, I'm not comfortable enough to be sure if I or the guide is wrong.
The guide I've followed is this: https://www.r-bloggers.com/analytic-hierarchy-process-ahp-with-the-ahp-package/.
(I run R version 3.3.2 (2016-10-31) -- "Sincere Pumpkin Patch")
1: I have (successfully) installed and loaded the AHP package using:
devtools::install_github("gluc/ahp", build_vignettes = install.packages("data.tree"))
2: I have (successfully) set working directory using:
setwd("myworkingdirectory")
3: I have attempted (PROBLEM) loaded the file to a variable using:
myahp <- LoadFile("myAHPfile.txt")
Error: could not find function "LoadFile"
3x: As diagnosis I run:
getAnywhere("LoadFile")
no object named ‘LoadFile’ was found
For your information: Step 3x is inspired by this SO answer (Error: could not find function ... in R)
Can someone tell me what I am doing wrong? I greatly appreciate any help.
Both. The guide refers to an old version of the gap package from github. With the latest version from cran (0.2.11), the function is now called Load, and the file format has changed.
If you just want to goof around with the package, I can recommend the online app at ipub.com.
If you insist on following the guide, make sure you get version 0.1.1 from github
