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

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

Dear Paul and others,
 
It also happens with the examples from Hadley geom_tile() on:
http://had.co.nz/ggplot2/geom_tile.html <http://had.co.nz/ggplot2/geom_tile.html> 
 
With this example I do not get the white lines: 
 
p <- ggplot(data = tot, mapping = aes(x = temp, y = precip))
p + layer(data = tot, mapping = aes(colour = dis, fill = dis),
    geom = "tile", stat = "identity")
 
But in this example I don't have the colours going from red (10000) to white, to blue (22000).

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

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

Subject: Re: [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
