To save a plot in R, follow these steps.
- Call a function to open a new graphics file, such as png(), jpg(), bmp(), or tiff().
- In the next step, call the plot() function to generate the graphics image.
- At last, call the dev.off() function to close the graphics file.
If you don’t provide an external path, it will save in your current directory.
png(filename = "mp.png", width = 625, height = 400)
plot(pressure, col = "red", pch = 19, type = "b",
main = "Vapor Pressure of Mercury",
xlab = "Temperature (deg C)",
ylab = "Pressure (mm of Hg)")
dev.off()Output
You check the downloaded PNG file inside your current directory.
Save as a Jpeg image
To save a plot as a jpeg image, you can use the “jpeg()” function.
jpeg(filename = "mp.jpg", width = 625, height = 400)
plot(pressure,
col = "red", pch = 19, type = "b",
main = "Vapor Pressure of Mercury",
xlab = "Temperature (deg C)",
ylab = "Pressure (mm of Hg)"
)
dev.off()Output
Save as bmp image
We can specify the size of our image in inch, cm, or mm with the argument units and specify ppi with res.
bmp(
file = "plot3.bmp",
width = 6, height = 4, units = "in", res = 100
)
plot(pressure,
col = "red", pch = 19, type = "b",
main = "Vapor Pressure of Mercury",
xlab = "Temperature (deg C)",
ylab = "Pressure (mm of Hg)"
)
dev.off()Output
Save as tiff image
To save in the tiff format, we only need to change the first line to tiff(filename = “plot3”).
tiff(
file = "plot3.tiff",
width = 6, height = 4, units = "in", res = 100
)
plot(pressure,
col = "red", pch = 19, type = "b",
main = "Vapor Pressure of Mercury",
xlab = "Temperature (deg C)",
ylab = "Pressure (mm of Hg)"
)
dev.off()That’s it.
