Hello, everyone, I have installed R successfully. But when I install the ShortRead with the command: source("http://www.bioconductor.org/biocLite.R") biocLite("ShortRead") I met the problem: g++ -I/bigstor2/wei/lib64/R/include -I/usr/local/include -I"/bigstor2/wei/lib64/R/library/IRanges/include" -I"/bigstor2/wei/lib64/R/library/Biostrings/include" -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DSIZEOF_UNSIGNED_LONG=8 -DHAVE_LIBZ=1 -fpic -g -O2 -c readBfaToc.cc -o readBfaToc.o /bin/sh: g++: command not found make: *** [readBfaToc.o] Error 127 ERROR: compilation failed for package 'ShortRead' * removing '/bigstor2/wei/lib64/R/library/ShortRead' * restoring previous '/bigstor2/wei/lib64/R/library/ShortRead' The downloaded packages are in '/tmp/RtmpbuyOyI/downloaded_packages' Updating HTML index of packages in '.Library' Making packages.html ... done Warning message: In install.packages(pkgs = pkgs, repos = repos, ...) : installation of package 'ShortRead' had non-zero exit status What should I do next?
