ggplot2 version 0.9.3 is giving me an error

[Mike Dylan]

I just installed ggplot2 verstion 0.9.3 and giving me this error. Any ideas what might be wrong? Anybody seen this yet?

 

Error in rename(x, .base_to_ggplot, warn_missing = FALSE) :
  could not find function "revalue"

[Mike Dylan]

I found what the problem was. I had to update plyr as well. I am not getting any error but when I do this: ggplot(mtcars, aes(wt, mpg)) + geom_bar(stat = "identity")

 

I get a blank graph, not data points. Any ideas?

Hi Mike,

This may or may not be helpful, but the command you posted about generates a plot with bars for me (i.e. not nothing as you experienced).  However, I do get the following warning message:

Warning message:
position_stack requires constant width: output may be incorrect

My session info is below.  Maybe you still need to update some packages???

Cheers,
Steve.

Hi:

As found in several posts on this group today, you need to reinstall
ggplot2 and plyr in a fresh R session, and it's probably safer to do
the same with scales and gtable:

install.packages(c("plyr", "ggplot2", "scales", "gtable"))

If you add geom_point() to this graph, you'll discover that there are
two values of wt that have replicate mpg values, and that's the source
of the warning (e.g., at the point of the maximum spike).

It looks like this is bug, which I've filed here:

  https://github.com/hadley/ggplot2/issues/739

It was introduced in the process of fixing another bug. :(

After updating to ggplot2_0.9.3, previous code used to make summary plots (using stat_summary) no longer work. I get the error message "Each group consist of only one observation. Do you need to adjust the group aesthetic?". My data has more than one observation for each group.  

I've tried to recreate the error using the mtcars data.

Any suggestions on how to properly create these summary plots would be greatly appreciated.

 

p <- ggplot(mtcars, aes(cyl,hp, colour = factor(gear))) 

p <- p + geom_point()

p <- p + stat_summary(aes(group = factor(gear)), fun.y = mean, geom = "line")

p

As a workaround, I'd suggest summarizing the data by hand using ddply:

library(plyr)

mtcars_m <- ddply(mtcars, c("cyl", "gear"), summarise, hp = mean(hp))

ggplot(mtcars, aes(cyl,hp, colour = factor(gear))) +

    geom_point() +

    geom_line(data=mtcars_m)

Try it with the versions.

Any thoughts about that?

Are you running this with a clean R session, without any packages loaded? If you include your sessionInfo, that would help to diagnose the problem.
