R save table as image

Question

I would like to export a data frame as a (png) image. I\'ve tried with this code, but the table get clipped vertically.

library(ggplot2)
library(gridExtra)

         


        

Answer 1

You can do like this:

library(gridExtra)
png("test.png", height = 50*nrow(df), width = 200*ncol(df))
grid.table(df)
dev.off()

Answer 2

You can change this behavior by specifying a height and width.

png("test.png", height=1000, width=200)
p<-tableGrob(df)
grid.arrange(p)
dev.off()

Anyway, it is usually not very helpful to save tables as pictures.

Answer 3

This works just fine:

library(gridExtra)

df = data.frame("variables" = c("d_agr","d_def","d_frig","d_hidro","d_roads","d_silos"),
"coeficient" = c(0.18,0.19,-0.01,-0.25,-0.17,0.09))

png("output.png", width=480,height=480,bg = "white")
grid.table(df)
dev.off()
