Hi,
I'm just starting to learn how to use R and I'm trying to create a
histogram with 7 breaks. This is my code so far:
dat=read.table("titanic.csv",header=TRUE,sep=",",na.string=".")
age=dat$Age
breaks=seq(min(age),max(age),length=7)
hist(age,breaks,freq=FALSE)
I don't know why, but on the fourth line it always gives this error:
Error in if (from == to) rep.int(from, length.out) else as.vector(c(from, :
missing value where TRUE/FALSE needed
What am I doing wrong? I know the data itself does have a lot of NA
values for age, would this be the problem?
Thanks,
CZ
