[R] ggplot with geom_tile

Dear R-users,
 
I am trying to make a plot with ggplot-geom_tile(), but cannot remove some
unwanted (white) lines through my plot.
 
Below a reproducible example: 
 
#####
library(ggplot2)
tot=as.data.frame(rep(seq(-50,50,5),each=21))
names(tot)="precip"
temp=rep(seq(-5,5,0.5),21)
tot$temp=temp
 
disc=array(dim=c(21,21))  
  for(i in 1:21){
    for(y in 1:21){
temp<- rev(seq(10000+((i-1)*500),12000+((i-1)*500),100))
disc[i,y]=temp[y]
  }}
  
disc1=t(disc)
bla=as.vector(disc1)
tot$dis=bla
 
cols=c("darkred"," white"," darkblue")
 
p <- ggplot(tot, aes(x=temp, y=precip,group=dis))
p+geom_tile(aes(fill=dis)) + scale_fill_gradientn(colours=cols)
###
 
This creates the plot that I want, but with white horizontal and vertical lines
that I do not need. I have tried different things, but have not found the
solution. Can you help me with this problem?
 
Kind regards,
 
Saskia van Pelt

[R] ggplot with geom_tile

Dear Saskia,

Thank you for the reproducible example, that helps a lot. I pasted you
code into R and got a perfectly fine image. You need to provide us with
your sessionInfo(). Mine is listed at the end of the mail. I seem to
remember having this problem with R 2.12. Therefore updating R might be
a good option.

hope this helps,
Paul

[R] ggplot with geom_tile

Dear Saskia,

If you mean the grid lines around the edge then they can be removed by using the
following:

p <- ggplot(tot, aes(x=temp, y=precip,group=dis))
p+geom_tile(aes(fill=dis)) + scale_fill_gradientn(colours=cols) +
scale_x_continuous(expand = c(0,0)) +
scale_y_continuous(expand = c(0,0))

I hope this helps

I remain at your disposal should you have any questions.

Best regards,

Frederic Andrieu

[R] ggplot with geom_tile

Dear Frederic,
 
No this was not the problem, the problem are horizontal and vertical white lines
in the figure. But the problem is gone when I save the figure and reopen it (in
another program), so I think the problem is only with my direct plot outputs.
Thanks for your help.
 
Kind regards,
Saskia
