Set two digits for correlogram, but some values were rounded up to one
I tried to create a correlogram with all values having two decimal places, but some of them still only have one.
I used both codes but didn't help
The first attempt seems ok, despite you are not using the right function, corr seems not exists:
library(corrplot) M <- mtcars # one digit corrplot(round(cor(M),1), method = "number") M <- mtcars # two digits corrplot(round(cor(M),s), method = "number")
Despite it seems you can't go over 3 digits.
