Here is an R tip. Need to quote a lot of names at once? Use qc().
This is particularly useful in selecting columns from data.frames:
library("wrapr") # get qc() definition
head(mtcars[, qc(mpg, cyl, wt)])
# mpg cyl wt
# Mazda RX4 21.0 6 2.620
# Mazda RX4 Wag 21.0 6 2.875
# Datsun 710 22.8 4 2.320
# Hornet 4 Drive 21.4 6 3.215
# Hornet Sportabout 18.7 8 3.440
# Valiant 18.1 6 3.460
Or even to install many packages at once:
install.packages(qc(vtreat, cdata, WVPlots))
# shorter than the alternative:
# install.packages(c("vtreat", "cdata", "WVPlots"))
