Error in corrMat[tf, targets] : subscript out of bounds

[KabitaBaral1]

Hi,

I ran into the error:
Error in corrMat[tf, targets] : subscript out of bounds

right in this step and it still persists even when I changed code from :
tfModules_withCorr_byTF <- lapply(tfModules_byTF[tfs], function(tfGeneSets)
{
tf <- as.character(unique(tfGeneSets$TF))
targets <- as.character(tfGeneSets$Target)
cbind(tfGeneSets, corr=c(as.numeric(corrMat[tf,targets] > 0.03) - as.numeric(corrMat[tf,targets] < -0.03)))
})

to:
tfModules_withCorr_byTF <- lapply(tfModules_byTF[tfs], function(tfGeneSets)
{
tf <- unique(tfGeneSets$TF)
targets <- tfGeneSets$Target
targets <- as.character(tfGeneSets$Target)
cbind(tfGeneSets, corr=c(as.numeric(corrMat[tf,targets] > 0.03) - as.numeric(corrMat[tf,targets] < -0.03)))
})

as suggested. Any idea on what might be the reason behind it?

Thank you
