I have used the corrplot as below, but as you can see I need to enlarge the font size of numbers inside the circles and then the plot title is not in a correct position and font size(not visible completely) but I can not find the parameters for them. I will be grateful if you could help.
library(corrplot)
png(height=1200, width=1200, file="overlap.png")
col1 <-rainbow(100, s = 1, v = 1, start = 0, end = 0.9, alpha = 1)
test <- matrix(data=c(20:60),nrow=7,ncol=7)
corrplot(test,tl.cex=3,title="Overlaps Between methods",
method="circle",is.corr=FALSE,type="full",
cl.lim=c(10,100),cl.cex=2,addgrid.col="red",
addshade="positive",col=col1, diag=FALSE,
addCoef.col = rgb(0,0,0, alpha = 0.6)
)
dev.off()
The problem seems to be with the png()
with the height=1200
and width=1200
options you provide. Try changing that line to:
png(height=1200, width=1200, pointsize=25, file="overlap.png")
The default pointsize = 12
somehow reduces the fonts of the labels
and title
, for some reason.
Edit: To see the title properly add this parameter to your corrplot
:
mar=c(0,0,1,0)
So the entire command set is:
library(corrplot)
png(height=1200, width=1200, pointsize=25, file="overlap.png")
col1 <-rainbow(100, s = 1, v = 1, start = 0, end = 0.9, alpha = 1)
test <- matrix(data=c(20:60),nrow=7,ncol=7)
corrplot(test,tl.cex=3,title="Overlaps Between methods",
method="circle",is.corr=FALSE,type="full",
cl.lim=c(10,100),cl.cex=2,addgrid.col=
"red",addshade="positive",col=col1, addCoef.col = rgb(0,0,0, alpha =
0.6), mar=c(0,0,1,0), diag= FALSE)
dev.off()
