Using paste in R -

i have question regarding utilize of paste in r

a<-c(1,2,3,5,5,6,7,8) b<-c(2,3,5,6,2,3,6,7) d<-c(2,8,4,6,3,7,3,5) df<-data.frame(a,b) cbind(df,sugar=d)

using above code, got this:

> b sugar 1 1 2 2 2 2 3 8 3 3 5 4 4 5 6 6 5 5 2 3 6 6 3 7 7 7 6 3 8 8 7 5

however, wonder why couldn't same results using paste function:

name<-c("sugar","salt","fat") cbind(df,paste(name[1])=d)

any help much appreciated!!

if need create new column name stored in object, try

 df[name[1]] <- d  df  #  b sugar  #1 1 2     2  #2 2 3     8  #3 3 5     4  #4 5 6     6  #5 5 2     3  #6 6 3     7  #7 7 6     3  #8 8 7     5

another alternative might utilize assign

assign('df', `[[<-`(df, name[1], value=d))

r paste
