cbind a dataframe with an empty dataframe - cbind.fill?

Question

I think I\'m looking for an analog of rbind.fill (in Hadley\'s plyr package) for cbind. I looked, but there is no cbind.fill

Answer 1

We can use a list instead of data.frame and convert it to a data.frame at the end. For instance:

df = list()
df2 = data.frame(col1 = 1:3, col2 = c('a','b','c'))
df = as.data.frame(cbind(df, as.matrix(df2)))
df

#   col1 col2
# 1    1    a
# 2    2    b
# 3    3    c
