[Rcpp-devel] Calling ggsave or pdf from RInside

[Michael Morrison]

Thanks again Dirk, is there a way that I can specify the root R directory?
I want to keep the working directory as is but when a library folder is
referenced as in the case with grDevices, i would like it to use
$(R_HOME)\library\grDevices\.... The root R folder isn't being picked up
correctly. I do have a $R_HOME  environment variable set up but it appears
not be used. Here's the script that i'm running via calls to the RInside
library, each call works until I get to ggsave(...) and at that point i get
the error message about not being able to find the file
'?,x`/library/grDevices/afm/Helvetica.afm'

require(graphics)
library("ggplot2")
nmmaps<-read.csv("C:/path/to/datafiles/data.csv",as.is=T)
nmmaps$date<-as.Date(nmmaps$date)
nmmaps<-nmmaps[nmmaps$date>as.Date("1996-12-31"),]
nmmaps$year<-substring(nmmaps$date,1,4)
head(nmmaps)
ggplot(nmmaps,aes(date,temp, color=factor(season)))+geom_point()

ggsave("C:/Path/to/file/myimage.pdf",
encoding="C:/R/R-3.2.4/library/grDevices/enc/WinAnsi")


Thank you,
Michael
