Answer 1

If you want to save a plot, in R programming, then you need to perform the following steps:

1. First, open a file, using png() or bmp() or pdf() format.
2. Plot your model
3. Close the file using dev.off()

The following is an example code that can be implemented for saving the plot to a png file:

fit <- lm(some ~ model)

png(filename="your/file/location/name.png")

plot(fit)

dev.off()
