Sub- or superscript in factorial variable - possible?
...the different
treatments in a boxplot.
Fot title, xlab and ylab sub- and superscript is no problem, but for the
different treatments of the following example I cannot get subscript.
Example:
weight <- c(6,5,7,2,7,3,9,4,2,7,8,9,2,3,4,5)
treatments <- as.factor(rep(c('Control', 'P2O5','K2SO4','CaSO4'),4))
data <- data.frame(treatments,weight)
boxplot(data$weight~data$treatments)
If I apply expression(P[2]...) I get "unimplemented type 'expression'
in 'HashTableSetup' ".
If there is a solution for this in base graphics or ggplo...

Calling Data frame objects with spaces in their names

I have also tried using . or _ instead of the space and have obtained no
succes. How do I
