Hello R-helpers,

I have 10 dataframes (named data1, data2, ... data10) and I would like to
add 5 new columns to each dataframe using the following code:

data1$LogDepth<-log10(data1[,2]/data1[,4])
data1$LogArea<-log10(data1[,3]/data1[,5])
data1$p<-2*data1[,6]/data1[,7]
data1$Exp<-data1[,2]^(2/data1[,8])
data1$s<-data1[,3]/data1[,9]

...but I would prefer not to repeat this chunk of code 10 times!

I have struggled with setting up a loop to apply these 5 lines of code to
each of the 10 dataframes, but I'm not having much luck.

Any help would be much appreciated.

Thank you, Mark
