Hi I tried a code from one of you for drawing a barplot with error bar.
But it didn't work, I am sure that the code provide should work (the figure produced is exactly what I wanted)
Here is the code, did I miss something?
> my.df <- read.table(text = "group N val sd se ci

I had that message:
Error in rename(x, .base_to_ggplot, warn_missing = FALSE) :
could not find function "revalue"
revalue
is a plyr
function which has been introduced 5 months ago. Probably you are running an older version than that. Updating plyr
and ggplot2
should fix that problem.
