Colorizing different individuals with fviz

Mon, Mar 29, 2021 2:33 PM

I understand that I came across this error after that


ind <- get_famd_ind(res.famd)
fviz_famd_ind(res.famd,
              col.ind = ifelse(ind>10,"red","black"),
              repel = TRUE)


Error in ifelse(ind > 10, "red", "black") :
  'list' object cannot be coerced to type 'double'
Calls: fviz_famd_ind -> %in% -> ifelse



I guess ind has (x,y) type and hence "ind>10" is not valid.

I also tried


col.ind = ifelse(ind.x>10,"red","black"),


But got the same error.

Any idea about that?

That error means that fviz_famd_ind has more than one argument that
starts with 'col' and you must type a more complete name to
disambiguate it.  Perhaps col.ind=ifelse(...)?

> args(factoextra::fviz_famd_ind)
function (X, axes = c(1, 2), geom = c("point", "text"),
    repel = FALSE, habillage = "none", palette = NULL,
    addEllipses = FALSE, col.ind = "blue", col.ind.sup = "darkblue",
    alpha.ind = 1, shape.ind = 19, col.quali.var = "black",
    select.ind = list(name = NULL, cos2 = NULL, contrib = NULL),
    gradient.cols = NULL, ...)
