Hello all,

I am having some trouble with the effectsize package in R. I am trying to

convert Z scores to percentiles using the convert_z_to_percentile command.

This same code (below) has worked for 3 other variables, but not these 2

variables

However, when I use the function to convert other z scores to percentiles,

I get numbers that are exponential (e.g., 1.877030e+01) instead of a

percentile. Has this happened to anyone else, and if so, how were you able

to fix it?

Here is my code:

#generate z-scores for SSPA using the scale() function - this part of the

code is successful

dat$varA_z <- scale(dat$varA_tot, center = TRUE, scale = TRUE)

dat$varB_z <- scale(dat$varB_tot, center = TRUE, scale = TRUE)

#Convert z-scores to percentile for UPSA using effectsize package tool,

convert_z_to_percentile

#for some reason this isn't working

dat$varA_per <- (convert_z_to_percentile(dat$varA_z)*100)

dat$varB_per <- (convert_z_to_percentile(dat$varB_z)*100)

Thank you in advance for any help you may be able to offer!

Emma
