Error in eval(predvars, data, env)

[JDBLab]

Hello,
Thank you for this package. Its really helpful. I am exactly following the tutorial. However, I am getting the following error. Could you please help me with the following issue-

fit_rf <- randomForest(D3~., data = Z1_D3)
Error in eval(predvars, data, env) : object 'NKX2-2' not found
D3_tf_top10 <- importance(fit_rf)[order(importance(fit_rf)[, 1], decreasing = T), ][1:10]
Error in importance(fit_rf) : object 'fit_rf' not found

Hi,
Thank you for trying our tool!
It looks like the issue about the object name. Could you please check the TF names in Z1_D3? If the there is ‘'NKX2-2’, try to change it to ''NKX2.2' and run again. Thank you.
