Correlation Matrix

[Rachele_Cecere]

My teammates and I are trying to plot the correlations between our variables on Knime.

We tried by implementing the ggcorr function through the Table to R node, however we can’t find a way to reduce label text size and the output image is incredibly small (see attachment).

We also tried using other R functions like ggcorrplot and ggcorrmixed, but still encountered the same issue.

As we have several variables, is there a way to create a clearer image?

Hi you could try adjust the cex parameter. Here’ s a sample.

corrplot(cor(test),
   method = "color", 
   addCoef.col="grey", 
   order = "AOE", 
   number.cex=0.75)

Apart from an R-based ggplot solution, what about the Heatmap node?
