ggplot problem . "Error unused argument(s) (n)"

[Andrew Clark]

Hi

 Any idea why I would be getting this error on glimmer 

http://glimmer.rstudio.com/pssguy/leagueTables/

whilst it is not occurring locally?

The files are the same on both and I have updated all packages

Here is relevant code

output$histogram1 <- renderPlot( {

    

     tit <- paste0("Point distribution after ",input$games1," games")

     print(ggplot(subset(tables_dt_print,Pl==input$games1), aes(x=Season, y=Pts)) +

               geom_boxplot()+coord_flip()  +ggtitle("tit") +ylab("Points")+xlab(""))

     })

I'm wondering if it might be related to scoping issues.

What happens if you replace

subset(tables_dt_print,Pl==input$games1)

with 

tables_dt_print[tables_dt_print$Pl==input$games1, ]

?

Maybe try using aes_string instead of aes.

Or maybe try defining the data.frame (as its distinct variable) before the call to ggplot.

  Thanks for suggestions all of which I tried unsuccesfully

  Definitely a good practice to create the data.frame in a reactive . I originally wrote this back in the day

and need to tidy up code

  The main issue I have is that it is the same ui,R, global.R and server.R on both the glimmer host

and my local machine and there are no issues on the latter

I copied your files to a different account on Glimmer and it worked fine. I thought maybe you had a different version of some library installed, but I can't seem to find any difference.

Still investigating...

It looks like you have plyr installed in your personal library but not ggplot2. ggplot2 is being taken from the site library (/usr/local/lib/R/site-library) where a version is being loaded that is not compatible with plyr 1.8.

You should either install ggplot2 in your personal library, or remove plyr from your personal library--either should fix it.

[Andrew Clark]

Thanks Joe

 i installed ggplot2 and that seems to have done trick

Just to clarify, in RStudio, clicking on the packages tab gives me a list of the packages on the site library?

Is best practice only to have in personal library those packages that are not already on site library?

[Joe Cheng]

I think the Packages tab gives you all the packages available to you, regardless of which library it comes from.

I don't think we have solidified any best practices yet with regard to package management. I put ggplot in the site library because many of our first users would run into "there is no package called 'ggplot2'" when attempting to write their first apps.
