[R] how to add any extra word to existing column heading in R

[John Kane]

names(height)  <-  paste0(names(height),".D1")

It would be better if you supplied the data using dput()

Have a lookt at https://github.com/hadley/devtools/wiki/Reproducibility for some suggestions on forming a good question.
