Re: [R] Col names in a data frame

it looks to me that the names are cranked through make.names for data frames case while that doesn't happen for matrices. Peeking into the `colnames<-` code supports this idea, but that in turn uses `names<-` which is a primitive and so defies further easy peeking. The data.frame function provides
