Hi everybody:
I have a question about reordering the levels of a factor (categorical variable). I want to create a barplot for an ordinal variable and i would like the order of the bars matchs with the hieranchical order of the categories; but the bars appear in alphabetic order. I can to solve this problem by mean of the R-integration nodes, but i would like to know if is posible to change the order within the KNIME enviroment, by using some node.
Kind regards!!
