Re: [R] Unable to Change Library Paths in R 3.5.1 in Windows 10

I've run into this problem on nearly every new machine I've touched in the past year. Here is a solution that has consistently worked for me in Windows 7 & 10: 1. Use .libPaths() to find where packages are being stored. 2. To change this path: Control Panel > search “View advanced sy

Re: [R] Keep on getting message errors when trying to install and load packages

[R] loading .rda file

Hi, I'm slowly migrating from SAS to R and - for the very first time - I'm working with a native .Rda data file (rather than importing data from other sources). When I load this .Rda file into the global environment using load("file path") I see a data.frame in the global environment called "mydat

[R] Code "tags"

Hi all, I'm trying to get organized about my R programming and I'm looking for a way to "tag" snippets of handy code that I go back to time and again. At the moment, I just plop .R files into a folder and rely on the file name to guide me. In desperation, I've taken to saving the same chunk as mul

[R] Assigning cores

Hi all, I'm working on a large simulation and I'm using the doParallel package to parallelize my work. I have 20 cores on my machine and would like to preserve some for day-to-day activities - word processing, sending emails, etc. I started by saving 1 core and it was clear that *everything* was
