Re: [R] Question about ggplot2 symbol and legend change

[Thierry Onkelinx]

Dear Luis,

Please don't post in HTML, it mangles the code.

You want something like

p + scale_shape_manual(values = c(16, 2))

Untested as you failed to provide a reproducible example.

[R] Question about ggplot2 symbol and legend change

[Luis Fernando García]

Dear R experts,

Maybe my question is too basic and I apologize for that. I am having an
issue currently by trying to change manually the symbols of the series. I
need to put them manually, instead of using the symbols that R gives by
default and produce a plot with the classic style. For example I need to
put the symbols 16 and 2, but I have been unable to do it so far. Also, I
need to remove the grey background from the seiries but I have been unable
to do it too.

Any help you can provide will be really helpful.

Below, I am providing the script as well as the picture I gio with it If
necessary I added the dataset.

Many thanks
