Another post for me that is simple and hopefully serves as an example for people trying to get blogging as #SQLNewBloggers.
I was trying to test an R script the other day and got this:
> library(randomForest) Error in library(randomForest) : there is no package called ‘randomForest’
A common error if you have just a base R installation. In my case, I’d installed R Studio, but nothing else. I knew that many packages are installed at CRAN, but I’d never gotten one. So I did.
The first step was a quick google for syntax. In this case, r-bloggers.com had a nice short piece. The install.packages() function is used.
I decided to just try it. In may case, I was happy to use the defaults for now. I ran:
> install.packages("randomForest") Installing package into ‘E:/Documents/R/win-library/3.3’ (as ‘lib’ is unspecified) trying URL 'https://mran.revolutionanalytics.com/snapshot/2016-11-01/bin/windows/contrib/3.3/randomForest_4.6-12.zip' Content type 'application/zip' length 177208 bytes (173 KB) downloaded 173 KB package ‘randomForest’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\Steve\AppData\Local\Temp\RtmpUl3h6d\downloaded_packages
After that, my library() function ran fine.
