Persistent invalid graphics state error when using ggplot2

Question

I believe my dataframe is okay and my code is okay   In fact  I have eliminated parts of the dataframe and most of the graphing code to make things as basic as possible   But still  I get   Error in  Call graphics C palette2   Call C palette2  NULL        invalid graphics state   What is wrong here   Here is the data     date   trt var val 1 8 2008    cc  sw5 0 2684138 1 8 2008    cc  sw15    0 2897586 1 8 2008    cc  sw5 0 2822414 2 8 2008    cc  sw5 0 2494583 2 8 2008    cc  sw5 0 2692917 2 8 2008    cc  sw15    0 2619167 2 8 2008    cc  sw5 0 204375 3 8 2008    cc  sw5 0 2430625 3 8 2008    cc  sw5 0 2654375 3 8 2008    cc  sw5 0 2509583 3 8 2008    cc  sw5 0 2055625 1 8 2008    ccw sw15    0 2212414 1 8 2008    ccw sw5 0 3613448 1 8 2008    ccw sw5 0 2607586 2 8 2008    ccw sw5 0 2087917 2 8 2008    ccw sw15    0 3390417 2 8 2008    ccw sw5 0 2436458 2 8 2008    ccw sw5 0 290875 3 8 2008    ccw sw5 0 20175 3 8 2008    ccw sw15    0 328875 3 8 2008    ccw sw5 0 2328958 3 8 2008    ccw sw5 0 2868958   When I work with this data  I specify dates like this   df lt -df order as Date df date format   d  m  Y     drop FALSE    and here I want to make a scatterplot   ggplot data   df aes x   date y   val       geom point aes group   trt

I solved this by clearing all the plots in the console and then making sure the plot area was large enough to accommodate what I was creating

I ran into this same error and solved it by running    dev off     and then running the plot again  I think the graphics device was messed up earlier somehow by exporting some graphics and it didn t get reset  This worked for me and it s simpler than reinstalling ggplot2

You likely don t need to reinstall ggplot2  Solution  go back to plot that didn t work previously  Take the below console output for example  The figure margins  the window that displays your plots  were too small to display the pairs MinusInner  plot  Then when I tried to make the next qplot  R was still hung up on previous error       pairs MinusInner    Error in plot new     figure margins too large   qplot Sample Type  BAE data MinusInner  geom  boxplot     Error in  Call graphics C palette2   Call C palette2  NULL          invalid graphics state   I fixed the first error by expanding the plot window and rerunning the pairs MinusInner  plot  Then blam  it worked       pairs MinusInner    qplot Sample Type  BAE data MinusInner  geom  boxplot

The solution is to simply reinstall ggplot2  Maybe there is an incompatibility between the R version you are using  and your installed version of ggplot2  Alternatively  something might have gone wrong while installing ggplot2 earlier  causing the issue you see

I found this to occur when you mix ggplot charts with plot charts in the same session  Using the  dev off  solution suggested by Paul solves the issue
