Question

This dataframe code :

which renders :

I'm attempting to transpose the rows to cols so a,b appear as :

X.a. a X.b. b

But this renders :

Can I use transpose function t() to change how data frame appears ?

You want to do this instead:

t(data.frame(lapply(letters[1:2] , f)))

Your code attempts to transpose the output of lapply, which is always a list.
