Hello all, If you have many subplots per combined plot you likely will want to save the plots at a larger size so the individual plots can be clearly seen. If we want to draw a plot within a for-loop, we need to wrap the print function around the R code creating the plot. Now to the real task – first I created a simple 100 x 4 matrix in a file called Main.R. If it’s a ggplot type graphic, easiest is probably to do something like: Doesn’t look too bad since you can still see the figure. Now you can type some basic Latex code to see if it works. Policy. Why does python use 'else' after for and while loops? 1. Korsocius • 160. At each iteration inside the loop, you want to construct a plot. plots aes_string which is useful when writing functions that create plots because you can use strings to define the aesthetic mappings, rather than having to mess around with expressions. PLOS ONE requires 300 ppi images in TIFF or EPS (encapsulated postscript) format. Another option is to specify a name like "samplo%03d.jpg", then the first plot will be saved to "samplo001.jpg", the second will be saved as "samplo002.jpg" and so forth.
