error trying plot_script.R

[JamalEH]

Dear all,
Thank you for sharing with us the R script to make perfect visualization of MoSEA outputs.

While trying the script on the test file I got the following error:
Attaching package: ‘reshape2’

The following objects are masked from ‘package:reshape’:

Error in -(robust_zscore) : invalid argument to unary operator
Calls: with -> with.default -> eval -> eval -> ifelse

I run the following command while specifying the minimum zscore at 1.96
Rscript plot_script.R ./test_file.tab ../plot_script 1 3 0.2 ./test_plot.png test_heatmap

Any help would be much appreciated!
Thank you in advance!

Best regards,
Jamal.
