Plotting on variables or cases

[fawda123]

Hi, here's an example using var_sub:

library(ggord)
library(ade4)
library(FactoMineR)

# dataset and ordination
data(tea, package = 'FactoMineR')
tea <- tea[, c('Tea', 'sugar', 'price', 'age_Q', 'sex')]
ord <- MCA(tea[, -1], graph = FALSE)

# regular
ggord(ord, tea$Tea)

# using var_sub
ggord(ord, tea$Tea, var_sub = c('p_upscale', '+60'))

Please provide a reproducible example if you're still having problems... or maybe I'm misinterpreting the problem. var_sub only removes vectors from the plot and does not change the underlying ordination. I think the better way to do this is to rerun the ordination with subsets of the original data, then plot.

Thanks,

Marcus
