Variable as a column name in data frame

Question

Is there any way to use string stored in variable as a column name in a new data frame? The expected result should be:

col.name <- \'col1\'
df <- data.fram         


        

Answer 1

I don't recommend you do this, but:

col.name <- 'col1'
eval(parse(text=paste0('data.frame(', col.name, '=1:4)')))
