Hi, i' d like to use R for simple calculations. I show you an examples to
make clear my help request
I' ve a file .csv like this (my real file is composed by 10.000 lines and 8
columns)
x y
3 4
1 7
I' ve imported in R correctly. Now i want create a new variable named "t"
and t is defined throught this relation:
t = 4 (second element on x column) * 4 (first element on y column)
in what way can i calculate t and print its value on an external file or,
better, append t values as a column on my original csv???
Thanks
Emanuele
