Hi,
It must be an easy question but how to boxplot a subset of data:
data = read.table("my_data.txt", header = T)
boxplot(data$var1[data$loc == "nice"]~data$loc_type[data$loc == "nice"])
#in this case, i want to display only the boxplot loc == "nice"
#doesn't display the boxplot of only loc == "nice". It also displays loc == "mice"
Hi Carol, It's them old factors sneakin' up on you. Try this: boxplot(data$var1[data$loc == "nice"]~ as.character(data$loc_type[data$loc == "nice"])) Jim
