Knitting error

[krittschof]

I have the following in my first chunk as always:

knitr::opts_chunk$set(echo = TRUE, message=F, warning=F, fig.align='center', fig.width=9 )

But when I knit, I receive the following error (see image):

Please advise. I Googled, and I am not finding a solution. Thanks, Kerri

Do you have an install.package() call in your RMD script somewhere?

Remember that you only need to install a package once, afterwards load it with the library() command. You should not include install commands in RMD files because they create errors while knitting.

The line number in bug tracking is helpful but not always accurate or precise, so take those with a grain of salt.

Typically it references the start line of a code chunk, and the error can be anywhere in the chunk.

Sometimes it is off completely if it is a complicated bug that results from dependencies in your code.

[krittschof]

I do remember. Thank you for that reminder. What I noticed when I install the following packages from the lecture:

install.packages( "plm" )
install.packages( "stargazer" )
install.packages( "scales" )
install.packages( "car" )
install.packages( "gplots" )
install.packages( "fastDummies" )

The last 3 (car, gplot, and fastDummies), I receive an error message saying that there are no packages call such. So when I left install.packages.... the error messages did not occur when I ran them. Hope that makes sense.

[krittschof]

I did change to library( ), except for the last 3 noted above

[krittschof]

Lastly, do we need the last 3 for the lab? Or is it just for the lecture notes?

[lecy]

Those packages are available via CRAN:

https://cran.r-project.org/web/packages/available_packages_by_name.html

Can you try opening an R shell and installing the packages?

R Studio sends you to their own server to install packages. Maybe these packages are not archived there?

Otherwise let me know what errors you get.

[lecy]

I don't know which you need for the lab off the top of my head, but it might be none.

[krittschof]

I have updated (Under Tools) and then installed the packages under Tools (they appear there), but when I run the library() of the packages, I receive "Error in library ("car") ; there is no package called 'car'. This error message occurs for gplots and fastDummies.

[krittschof]

I also receive this message: "WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:"

I closed out and did an update in R (appears not correctly) via the previous message.

[lecy]

The packages are not installing properly then.

Rtools is a separate install. I suspect if you install that first then try installing the other packages it will fix the issue.

If you don’t need the packages, though, skip it.

[lecy]

Skip it = just remove the library() calls for those packages from your RMD file.

[krittschof]

I had a colleague look at what was going on, It was Drop box that was inhibiting the install. He unlocked it, but R is still running through dropbox. Do you know how to stop that????

[lecy]

Interesting! I have not encountered this before.

What does it mean for something to run through Dropbox?

Program files are usually installed in a root directory.

C:\Program Files\R

If R is installed somewhere else, you might want to remove it and re-install in the root directory? That should happen by default, but maybe pay attention during the install process.

And packages are installed in your local library, which typically defaults to the documents folder:

C:\Users\username\Documents\R\win-library\4.0

I suspect this is your problem: packages, not the R software itself?

Are you archiving files in the Documents folder with Dropbox?

Do you have the option activated where you archive all files on your computer with Dropbox?

[krittschof]

I do not actively store in dropbox (well not my intention anyway), I will check your suggestion out above and let you know. Thank you.
