Hello,
Check the result of

And read

Hi Casey,
Yes, if there are missing values than you don't strictly speaking know
what the minimum value is. You need to tell min() and max() to exclude
missing, i.e.,
breaks=seq(min(age, na.rm=TRUE),max(age, na.rm=TRUE),length=7)
Best,

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 four
3 matches
