Any way to preserve spaces in names when calling transform()?

Question

Is there any way to preserve spaces in a data.frame's column names when calling transform()? Currently they get munged:

> transform(data.frame('a b'=1, check.names=F), `c d`=`a b`)
  a.b c.d
1   1   1

Answer 1

Just feed check.names=F into transform:

> transform(data.frame('a b'=1, check.names=F), `c d`=`a b`,check.names=F)
  a b c d
1   1   1

However, I don't see this mentioned in the documentation for ?transform!
