[R] how to add any extra word to existing column heading in R
Hello R experts,
I want to add some extra words to number to existing column header. Can
anybody tell me how to do that.
e.g. if I have a data.frame
Height.1 Height.2 Height.6 Height.8 Height.10 Height.11 Height.17
Height.20 Height.22 Height.31
MBR1 74 72 0 104 0 250 144
0 0 0
MBR2 0 94 0 150 0 250 158
0 0 0
MBR3 93 167 0 199 0 250 208
0 0 0
MBR4 146 106 0 165 0 250 135
0 0 0
MBR5 149 106 0 0 0 250 141

0 0 79
MBR8 89 70 0 114 0 250 211

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