Hi, So working with docker and rJava i have a freeze at the Xrs check there is a solution that is to use the --disable-Xrs option https://github.com/s-u/rJava/issues/63 but as i'am a beginner : install.packages("rJava", repos=' http://cran.us.r-project.org', configure.args ="--disable-Xrs") doesn't work and still freeze my install... So any help welcome. regards and thanks Bussiere [[alternative HTML version deleted]]
