lapply - How to apply log function to dataframe in R?

I have a dataframe named COMP with 24 columns in it. I would like to create another dataframe named COMPLog with log10 versions of all 24 columns/variables in it.

COMPLog <- lapply(COMP[,c(1:24)], function(x) log(x))

Error in log(x) : non-numeric argument to mathematical function

I've trawled through other questions and tried using df.log <- log(df) from one of the earlier questions, but I am unsure how to modify it for my situation. I've also tried mutate and transmute but I did not manage to get my code to work.

What code should I use to apply log10 to all of the variables in a dataframe? (and then to save it as another dataframe).
