This list is a collection of specific commands to do specific (pieces of) plots that I often need. Most of the commands use ggplot2.
Conventions: The data is assumed to be a data frame
called dat
, I’m using the pipe-operator notation, the
outcome of interest is called outcome
, variables are
var1
, var2
, etc. or just refered to as
varname
. ggplot library is assumed to be loaded for most
commands.
If one uses dashed/dotted/solid lines in lineplots, the default legend in ggplot is often not big enough to properly show the different lines. One can increase this with
where X is the length/width one wants.
ggplot shows legends alphabetically for non-factor variables. Easiest approach is to turn variable into factor and sort as needed.
