when I plot the grid there are some margins that I don't want it to be visible in my plot. how can I solve this problem?
here is an example:
Grid coordinates
grd.coor<- data.frame(lon=rep(seq(13,16.5,0.5), 13),lat=rep(seq(91,97,0.5),each=8))
library(ggplot2)
ggplot(grd.coor, aes(x=lon, y=lat))+geom_point()+
theme(panel.grid.minor = element_line(colour="white", size=0.5)) +
scale_y_continuous(minor_breaks = seq(91 , 97, .5), breaks = seq(91, 97, .5))+
scale_x_continuous(minor_breaks = seq(13,16.5,0.5), breaks = seq(13,16.5,0.5))
After running this code I get this plot
I want only the area inside the red square to be displayed without the margins.
If you definte grd.coor like this, do you get what you want?
grd.coor<-
data.frame(
lon=rep(seq(13.5,16,0.5), 11),
lat=rep(seq(91.5,96.5,0.5),each=6)
)

unfortunately it doesn't work, can you suggest something else which gives the desired outcome
It's not clear what it is you're hoping for -- could you produce an image that shows exactly what you want?
Not sure how to modify theme() arguments to do this, but here's a possibility:
ggplot(grd.coor, aes(x=lon, y=lat))+
theme_minimal() +
geom_rect(
aes(xmin = min(lon), xmax = max(lon), ymin = min(lat), ymax = max(lat)),
fill = 'grey90'
) +
geom_vline(aes(xintercept = lon), color = 'white', 'size' = 0.5) +
geom_hline(aes(yintercept = lat), color = 'white', 'size' = 0.5) +
geom_point()+
scale_y_continuous(minor_breaks = seq(91 , 97, .5), breaks = seq(91, 97, .5))+
scale_x_continuous(minor_breaks = seq(13,16.5,0.5), breaks = seq(13,16.5,0.5))
