In my_data I want to create new variables. I do not know how to give names to my new variables, taking into account that those new variables are inside the for loop.

for (i in 2:ncol(my_data)) {
sdev <- sd(my_data[,i])
my_data$colnames(my_data[i]) <- my_data[,i]/sd(my_data[,i])
}

I tried this way, but it doesn't work. There should be i new variables, and every variable should have different name. Thanks!

You can do this with `[[ ... ]]` `my_data[[colname_string]] <- code` – Dex Groves Oct 19 '16 at 13:44
It does not work, or I wrote the wrong code. Can you write a whole code? – Oct 19 '16 at 13:54
Something like this https://gist.github.com/DexGroves/f2a65e69b2bc8048e63a774b611bf646 – Dex Groves Oct 19 '16 at 13:56
This seems more fitting for StackOverflow. – Ami Tavory Oct 19 '16 at 14:04
