Error running DEqMS

[HYTang69]

Hello, I am new to DEqMS. I am trying to analyze MaxQuant data. I was able to follow the vignettes instructions to process the PXD000279 data. However, when I load my own proteinGroups.txt, I encountered an error running the command:

pep.count.table = data.frame(count = rowMins(as.matrix(df.prot[,19:24])), row.names = df.prot$Majority.protein.IDs)

Error in rowMins(as.matrix(df.prot[, 19:24])) : Argument 'x' cannot be logical.

I wonder if you have any idea what caused this error.

Thank you for your time!
