Thanks, Eldar! I installed Rtools from the website you sent. Then, per the subsequent error messages trying to install TwGeos, I also had to run: install.packages("SGAT"); install.packages("zoo"); devtools::install_github("SLisovski/TwGeos"); It looks like Twgeos is successfully loaded. > search() [1] ".GlobalEnv" "package:SGAT" "package:zoo" [4] "package:TwGeos" "package:stats" "package:graphics" [7] "package:grDevices" "package:utils" "package:datasets" [10] "package:methods" "Autoloads" "package:base" Now I just have to figure out how to use it! thanks! Dan

I'm just starting with handling the .lux files. I want to bring them into TwGeos in order generate the TAGS files for FlightR. I am following the directions from slisovski's GitHub for TwGeos. I'm running R version 3.5.2. I installed devtools package. When try to install TwGeos it fails. > devtools::install_github("SLisovski/TwGeos") Downloading GitHub repo SLisovski/TwGeos@master WARNING: Rtools is required to build R packages, but is not currently installed.
