...ion. It seems that is failing something obvious with the workspace. I am a newbie and here is my code: myk = function (x, centers, iter.max = 10, nstart = 1, algorithm = c("Hartigan-Wong", + "Lloyd", "Forgy", "MacQueen")) + { + do_one <- function(nmeth) { + Z <- switch(nmeth, { + Z <- .Fortran(R_kmns, as.double(x), as.integer(m), + as.integer(ncol(x)), centers = as.double(centers), + as.integer(k), c1 = integer(m), integer(m), nc = integer(k), + double(k), double(k), intege...

...5 [10,] 6 7 5 9 3 1 2 5 1 8 When I try to scale my data and perform kmeans clustering, I get the following errors: new <- scale(new) Error in colMeans(x, na.rm = TRUE) : 'x' must be numeric > cl <- kmeans(new, 4) Error in switch(nmeth, { : NA/NaN/Inf in foreign function call (arg 1) In addition: Warning message: In switch(nmeth, { : NAs introduced by coercion This is confusing to me since all of the data is numeric and there are no missing values. Is there something I need to do to my data to prepare it for kmeans? I have tried...

I am running a k-means clustering code in R : mydata_kmeans5 <- kmeans(mydata, centers=5).. But the problem is that the data is having some "NA" in it. So R is showing me a message :Error in switch(nmeth, { : NA/NaN/Inf in foreign function call (arg 1) In addition: Warning messages: 1: In switch(nmeth, { : NAs introduced by coercion 2: In switch(nmeth, { : NAs introduced by coercion... my objective is to find out the customers id who are falling in particular cluster say clst 1, clst2 etc...If I wa...
