The default color palette used by TraMineR
can get a maximum of 12 different colors, which is clearly insufficient in your case. Hence, you have to specify the color palette using the cpal
argument in seqdef
. The colorspace
package provides functions to get more than 12 colors.
To choose your 60 colors using a graphical interface:
library(colorspace)
pal <- choose_palette()
seqdef(..., cpal=pal)
Or to automatically get a list of colors, try
library(colorspace)
pal <- diverge_hcl(60)
seqdef(..., cpal=pal)
See ?diverge_hcl
for more options.
Hope this helps.
