Re: [R] withr::set_makevars

withr:::set_makevars() can give that error if the makefile named by the 'old_path' argument (default "~/.R/Makevars) contains more than one definition of a variable of the form 'name=value'. You can see what file it is reading and its contents by using the trace() function:

Re: [R] rgdal error when trying to import raster

Indeed, Ben, but the question was something more like it is not a Dependency, just Suggested, so why the error... John: If you read the Introduction to the 'raster' package vignette, it indicates that some input formats are supported within the raster package and some rely on other packages.

[R] withr::set_makevars

Hi All; This problem has come about from trying to learn some of the review practices recommend by rOpensci. One of them is to use the package goodpractice. After installing goodpractice, it kept failing on my own packages which are under development, and I was concerned something was funny

Re: [R] rgdal error when trying to import raster

Hi, The message "there is no package called 'rgdal'" means that you don't have rgdal installed. https://cran.r-project.org/web/packages/rgdal/index.html Also, you will get very good patial-centric help if you subscribed to r-sig-geo here https://stat.ethz.ch/mailman/listinfo/r-sig-geo

Re: [R] Interesting behavior of lm() with small, problematic data sets

Indeed (version-specific). With R 3.4.1 on linux, I get coefficients and residuals that are numerically exact, F-statistic = NaN, p-value = NA, R-squared = NaN, etc. All of which is what ought to happen, given that the response variable (y) is not actually variable. ---JRG John R. Gleason On
