Hello, it looks like this is what you want. year <- c(1970:1980) > snow <- sample(10,length(year),replace=T) > snow [1] 3 3 3 4 8 3 2 6 6 6 10 > year [1] 1970 1971 1972 1973 1974 1975 1976 1977 1978 1979 1980 > mydata <- data.frame(year,snow) > attach(mydata) > barplot(snow,names.arg=year,las=2)
for a histogram of snow you might try something like this hist(snow,breaks=c((min(snow)-0.5):(max(snow)+0.5))) Felix (who is a newbie himself, so excuse me please if i didnt get your problem) Am Mittwoch, 4.
