Save ggplot with a function

Question

I would like to create a function to save plots (from ggplot).

Here is a data frame:

### creating data frame
music <- c(\"Blues\", \"Hip-         


        

Answer 1

Following was useful for me, may be for someone else as well. One can save the last plot without explicitly referring it as well.

ggsave("filename.pdf",  # jpg, png, eps, tex, etc.
       plot = last_plot(), # or an explicit ggplot object name,
       width = 7, height = 5, 
       units = "in", # other options c("in", "cm", "mm"), 
       dpi = 300)
