Error on installation

[aikaterinimanousidou]

Hi! I'm trying to install this package and I have tried 3 different and all have failed me so I was wondering if there is some type of file missing in the package.

1. I tried through Rstudio by install.packages("quantregForest) and I got the following error Error in install.packages : missing value where TRUE/FALSE needed
2. I tried through Rstudio again but this time using devtools by install_github("lorismichel/quantregForest") and I got the following error Warning in grepl(e, files, perl = TRUE, ignore.case = TRUE) : PCRE pattern compilation error 'unrecognized character follows \' at 'quantregForest\.pdf$' Error in grepl(e, files, perl = TRUE, ignore.case = TRUE) : invalid regular expression '^\quantregForest\.pdf$' Execution halted Error: Failed to install 'quantregForest' from GitHub: System command 'Rcmd.exe' failed, exit status: 1, stdout & stderr were printed
3. I tried both 1 and 2 through Rgui too but it didn't work either.

Please let me know if I did something wrong or if I'm missing something. Thank you in advance Aikaterini

I can confirm it is broken:

@aikaterinimanousidou Ok, just send the corrupt .Rbuildignore to the trash bin (and perhaps a useless appveyor.yml too), and everything works.
