unknown error for Rscript

[kazumaxneo]

Hello.
I have read the published paper. The comparison of normalization methods is very interesting.
I think I can learn a lot from it.
I tried to use the released R script to check the effect of CTF and CUF normalization, but the script did not work.
What could be the problem?
