Dear R-users,

I'm struggling with APA formatted two way BAR-charts according to apa-style
i should have the legend in the background of my plot (so above the bars and
not beside the picture/plot itself) and the background should be completely
white without gridlines or what so ever. Could any one give me a hint or
solution? See Below for my commands

thank you so much,

Benjamin Telkamp (Email: inzichtel...@gmail.com, The Netherlands)

these are the commands used so far which just didn't give me what i wanted

library(ggplot2)
library(foreign)
install.packages("Hmisc")
DATA1<- read.spss(file=DATA1, use.value.labels=TRUE, to.data.frame=TRUE)
Bar_PD<- ggplot(DATA1, aes(Age_group, IRI_PD ))
Bar_PD + stat_summary(fun.y = mean, geom = "bar", fill = "Purple") +
stat_summary(fun.data = mean_cl_normal, geom = "errorbar", width = 0.2) +
labs (x = "Leeftijdsgroep", y = "IRI PD") + theme(plot.background =
element_rect(colour= "White"))

Hi Benjamin,
I'm not sure what you mean by a two way bar chart. If it is a grouped barplot in which the members of each group are defined by the levels of one discrete variable and the groups are defined by another discrete variable, the basic "barplot" function with an added legend should do what you want. Can you give an example such as an image on the internet that shows what you want?

Jim
