I am trying to use the functions ezPrecis and ezPlot from the ez library. I install the library without any problems:
install.packages(c("ez"))
and I import the library:
library(ez)
but when I run my code, e.g.
ezPrecis(d2)
I get the error:
Error: could not find function "ezPrecis"
and the same with ezPlot. Any ideas?
