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
