plotEXP #5

Closed lucas2chen closed 1 year ago

lucas2chen commented 1 year ago

When using the method plotEXP to draw a heat map with the correlation of each exposure to the principal components, is it possible to specify which type of correlation we are using, for example, Pearson or Spearman? I couldn't find this specification or function in the CODE.

The correlation plotted by this function is actually calculated by FactoMineR when calculating the PCA. More information here: http://factominer.free.fr/factomethods/principal-components-analysis.html
