RE: Error: could not find function "theme"

[Ito, Kaori (Groton)]

I think you have older version of R (and subsequently installed older version of ggplot)?

Try to see what version you have, type:

sessionInfo()

 

I have R-2.15.3 and ggplot2_0.9.3.1;  I don’t have any problem to run the code you posted below, but when I tested it with R-2.12.2 and ggplot2_0.8.9 then I got the same error as you have.

Subject: Error: could not find function "theme"

 

After installing and loading ggplot2; 

install.packages("ggplot2") 

library(ggplot2)

 

I tried the following code,

> p <- qplot(mpg, wt, data = mtcars)

> p + theme(panel.background = element_rect(colour = "pink"))

 

and got an error: Error: could not find function "theme"

 

Any help please?

Thnx

Nano
