Newbie question on subsets
Hi...
I'm working through the book, A Handbook of Statistical Analyses
using R by Everitt, and I'm trying to do the following (p. 19 of his
book):
boxplot(log(marketvalue)~country,
data = subset(Forbes2000,
country %in% c("United
Kingdom","Germany","India","Turkey")),
ylab="log(marketvalue",
varwidth=TRUE)
This *almost* works, but I'm getting ALL the countries on the x-ax...
