How to make the plots that are all the same color different?

#1

Dear community

I would like to change the plots that are all the same color different.

But I prefer the default color scheme.

So I wouldn't like to specify the colors of the plot.

How can I make plots be different colors and have a default color scheme?

x=read.csv("watakushi.csv",header=T,row.names=1)

library("vegan")

nmds=metaMDS(x,distance="bray")

nmds_xy=data.frame(nmds$points)

library("tidyverse")

ggplot(nmds_xy,aes(MDS1,MDS2))

+geom_point(size=3)

nmds_xy
           MDS1         MDS2
21N -0.34087362  0.101920607
21A -0.14167136 -0.001546407
21F  0.28444552  0.223030000
22H  0.26523581 -0.069376792
22N -0.14969636 -0.045022657
22F  0.08256002 -0.209004752

Have a look:

Thank you for your quick reply and kindness.

I'll look over them.

Can I ask you one more question?

How do I specify row name to change the plot color?

Do I have to convert watakushi.csv into some data frame?

Are there categories that you are using to colour the points? Are you hoping to colour using one of the other continuous variables?

Can you provide a reproducible example instead of a screenshot?
