r - RStudio Exporting Issues -

-

i have never needed export rstudio specific dimensions. producing graphs publication strict width of 2400 pixels. major problem have not used singular traditional plot have done. have customised graph various plots , segments. evaluate plot have been making it, have been looking @ zoomed in plot in rstudio.

so asking whether there way export zoomed in plot on rstudio png specified width (height, flexible with).

i have tried

dev.copy2pdf(device = "pdf", file = "test.pdf")

which didn't work had hoped.

if using ggplot, can use ggsave:

qplot(rating, data=movies, geom="histogram") ggsave("test.pdf", height=8, width=8)

the default dpi 300 300 dpi x 8 inches = 2400.

this should same in base plotting system:

pdf("boxplot.pdf", height=8, width=8) boxplot(mtcars$mpg) dev.off()
