sesame/sesamize Error: could not find function "pkgTest"

[altuda]

Hello,
I've run into an issue with sesamize, so I tried the vignette code and I am still getting the same error as with my data:

library(sesame)
library(FlowSorted.Blood.450k)
source("https://github.com/zwdzwd/sesamize/raw/main/sesamize.R")

grSet <- sesamize(FlowSorted.Blood.450k[,1:4])
Error in pkgTest("minfi") : could not find function "pkgTest"

Could you please provide some feedback and help?

Thank you so much for your effort and time.
