Hello,
how do you create a histogram with a data frame?
year snow.cover 1970 6.5 1971 12.0 1972 14.9 1973 10.0 1974 10.7 1975 7.9 ...
mydata=data.frame(year=c(1970,...),snow.cover=c(6.5,...))
hist(mydata) does not work.
I guess you are not going to create a histogram but a barplot as in:
barplot(mydata$snow.cover, mydata$year, names = mydata$year)

Many thanks.
