Save the plots as JPEG or PDF from jupyter notebook with R Kernel

Question

I'm having a trouble with saving the plots as jpeg or pdf format from R kernel of Jupyter Notebook.

Here's the code,

pdf("Hatdog.jpeg")
plot(x,y, col="green")
dev.off() 

I was wondering why the image is corrupted, which when I tried to open the actual file, it states that It looks like we don't support this file format.

Anyone having the same issue? How did you solved it? Thanks.

Answer 1

You are saving a pdf file with a -.jpg extension? To save as a jpeg:

# 1. Open jpeg file
jpeg("rplot.jpg", width = 350, height = 350)
# 2. Create the plot
plot(x = my_data$wt, y = my_data$mpg,
     pch = 16, frame = FALSE,
     xlab = "wt", ylab = "mpg", col = "#2E9FDF")
# 3. Close the file
dev.off()

To save as a pdf:

# Open a pdf file
pdf("rplot.pdf") 
# 2. Create a plot
plot(x = my_data$wt, y = my_data$mpg,
     pch = 16, frame = FALSE,
     xlab = "wt", ylab = "mpg", col = "#2E9FDF")
# Close the pdf file
dev.off()
