r - Using a loop in ggplot2 -

i trying create multiple boxplots in ggplot. need split continuous variables nominal variable (school). want omit single na's in data-frame dataso. want create boxplot every column , have name of column label. when use following code don't error message, no plots generated. ideas?

for(i in 1:length(dataso)) {   boxplot <- ggplot(na.omit (dataso), aes(school,i)) +   geom_boxplot() + labs(x = "school", y = names(dataso[i])) } 

i able generate 1 boxplot using code:

box2 <- ggplot(na.omit (dataso), aes(school, soirglobal)) box2 + geom_boxplot() + labs(x = "school", y = "soirglobal") 

i great boxplots 9 other variables in dataso

dataso <- subset(datafull, age >= 18, select=c(age, school, race, soir1:soir9))
