hi all:
Here's a dataframe(dat) and a vector(z):
dat:
x1 x2 x3
0.2 1.2 2.5
0.5 2 5
0.8 3 6.2
> z
[1] 10 100 100
I wanna do the following:
10*x1,100*x2,1000*x3
My solution is using the loop for z and dat(since the length of z is the same
as ncol of dat),which is tedious.
I wanna an efficient solution to do it .
Any help?
Many thanks!
My best
