A permanent error with densityClust package

Question

[zizigolu]

Hi,

Whatever I am trying to work with densityClust R package, I am facing this error

> irisClust <- densityClust(irisDist, gaussian=TRUE)
Distance cutoff calculated to 0.2767655 
Error in .Call("_densityClust_gaussianLocalDensity", PACKAGE = "densityClust",  : 
  "_densityClust_gaussianLocalDensity" not available for .Call() for package "densityClust"
Called from: gaussianLocalDensity(distance, attr(distance, "Size"), dc)

Any suggestion please? Thank you

Just tried, works fine with Windows7, R 3.4.2, densityClust_0.3.

library(densityClust)

irisDist <- dist(iris[,1:4])
irisClust <- densityClust(irisDist, gaussian=TRUE)
plot(irisClust) # Inspect clustering attributes to define thresholds
irisClust <- findClusters(irisClust, rho=2, delta=2)
plotMDS(irisClust)
split(iris[,5], irisClust$clusters)

Please provide output of sessionInfo().

Thank you but I have already tried this
