[R] extract columns using their names

[Adrian Dusa]

Hello,

Is there a way to extract multiple columns from a dataframe using their
names instead of their numbers?

Currently I use:

data2 <- data1[, c(1,3,9)]

And I am looking for something like

data2 <- data1[, c("XX","YY","ZZ")]


I use the same dataframe for many purposes, and I run codes that change
the order of the columns every time.

Many thanks,
Adrian
