Hello,
I am creating a 3D scatter plot with the cloud function. I ask it to
group my rows by a "Treatment" column (there are 4 different groups). I
need to know which points in the plot correspond to which rows (which
treatment). By default it assigns pchs and cols to each group. When I
try to define the colors or point shapes it seems to use the first color
and pch for both the first and last group. I've tried to add:
col = c("blue","red","orange","green"),
pch = c(20,20,22,22),
after the "cex" line.
The only think that seems to work and keep all four groups separate is
making
cex = c(1,2,3,4),
I cannot figure out what it combines the first and last of my groups
with the same point character and color. Any suggestions?
(Part of my code)
....
print(cloud(RMMdistMETAc3$points[,1] ~ RMMdistMETAc3$points[,2] *
RMMdistMETAc3$points[,3],
data = RMM,
cex = 0.8,
groups = Treatment,
screen = list(z = 10, x = -40, y = 3),
) .....
