Error when trying to run the first specific example

[yzfranci]

Hi,
I'm trying to use MINOTAUR for the first time, and I immediatly ran into an error while running the following example:

observations <- 1000
obsID <- seq(1, observations, by=1)
var1 <- rnorm(observations)
var2 <- rnorm(observations)
var3 <- rnorm(observations)
var4 <- rnorm(observations)
var5 <- rnorm(observations)
allVar <- cbind(obsID, var1, var2, var3, var4, var5)
columns <- 2:6

Md <- Mahalanobis(dfv=allVar, column.nums=columns)

which gave me this message:

Error in if (class(try(dfv[, column.nums], silent = TRUE)) == "try-error") stop("column.nums must contain valid indexes for choosing columns in dfv") :
the condition has length > 1

My R version is 4.2.1 (2022-06-23), and I am not sure if that matters but I had to install MINOTAUR with build_vignettes = FALSE, because I would get this error message otherwise:

E creating vignettes (29.1s)

Quitting from lines 124-149 [unnamed-chunk-4] (MINOTAUR.Rmd)

Thanks for your help
