The fifth column has a different name for each csv. The number of rows is different. The

Evaluate values in `Sys.setenv`
Hi all, I would like to know if there is any way to evaluate the values in `Sys.setenv` before setting the environment variables. For example, if we want to add a path to the environment variable `PATH`, we can do this in a terminal ``` > export PATH=~/mypath:$PATH > echo $PATH /Users/jeff/mypath:... ``` However, this style of assignment is not allowed in `Sys.setenv`, it treats its

system command to a specific shell (bash)

I found the shell command ( http://www.stat.ucl.ac.be/ISdidactique/Rhelp/library/base/html/shell.html) but it seems to be disappeared in current versions of R? I am running all this from R CMD BATCH with "system" calls to other R scripts. For a little more info, I'm

Identify points that lie within polygon
I have a complex 2D polygon with thousands of vertices, and I'd like to be able to identify points from a large set contained within the polygon, and was wondering if there might be an efficient way of doing this? Any advice would be useful! Here is a small example of what I mean: # make polygon v1<-c(0,1,1,2,1,3,6,7) v2<-c(1,3,3,5,6,7,8,9) plot(v1, v2, type = "n" )

[nbdkit PATCH v6] vddk: Add re-exec with altered environment
In the next patch, we want to get rid of the requirement for the user to supply LD_LIBRARY_PATH pointing to vddk libs, if we can derive it ourselves from libdir. However, VDDK itself requires LD_LIBRARY_PATH to be set (because it tries to load libraries that in turn depend on a bare library name, which no manner of dlopen() hacking can work around, and implementing la_objsearch() is no better for
