panel.border in ggplot2 ploting thicker lines in bottom and right side of the plot

[Geraldo Carvalho Júnior]

Does anybody have any idea why this happens?

Following is a reproducible example:

library(sp)

library(ggplot2)

x <- runif(30, 587093, 587152)

y <- runif(30, 7848525, 7848605)

coor <- data.frame(x,y)

a1 <- ggplot() + geom_point(data=coor, mapping=aes(x=x, y=y), pch=3)

b1 <- a1 + theme_bw() + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank())

c1 <- b1 + theme(axis.title.y = element_blank()) + theme(axis.title.x = element_blank()) + theme(legend.title=element_blank()) + theme(legend.key= element_rect(colour = "white"))

d1 <- c1 + ggtitle("B") + theme(plot.title = element_text(face="bold", hjust=0.5, vjust=0.6)) + theme(panel.border = element_rect(colour="black", size=1))

Thanks!

Could you attach a photo? I don't see anything wrong on my end.

Apparently, this behaviour stops when in theme(panel.border =
element_rect(colour="black",
>> size=1)) size is set to anything else than "1".
