rloadest not working

[dsaleh19]

Hello I just got a new lap top, I installed all the packages I need to run loadest using this code:

options(repos = c( ldeciccousgs = 'https://ldecicco-usgs.r-universe.dev',
 CRAN = 'https://cloud.r-project.org'))
install.packages('rloadest')

All seams to work well. My issue is when I run through my rloadest mode (which is running fin on my old laptop) I get an error when I run this line of code:
preds_conc_lr1 <- predConc(pTHg_Yolo_lr1, YoloQ, by= "day", allow.incomplete= TRUE )

This is the error:
Error in match.arg("by", ByOpt) : 'arg' should be one of “unit”, “day”

I really don't know why this is happening the code is working fin on my old laptop.
Any ideas on how to fix this please?
