convert multiple data frame columns to numeric vector

Question

I have this dataframe df:

C           S

F           7.6
O           8
T           9

I want to convert it to a numeric vector like this. Not wide format

F      O       T
7.6    8       9

I want to check with class(df) after and see numeric

How can I do that?

Ah, I see the distinction, apologies ( ofc w your edit it is now abundantly clear as well :) ) — duckmayr, Jan 19 '21 at 13:52

You can use setNames to create a named vector :

vec <- setNames(df$S, df$C)
vec 
# F   O   T 
#7.6 8.0 9.0 

class(vec)
#[1] "numeric"
