Iñaki:
-Optimized document structure, variable naming
-Created a function to print plots in an outside directory
-Other plot things
Jaume:
-Fixed bug from acm (didn't work for me, program crashed) We can change it back by commenting my ac1 <- acm(dcat,dict) and de-comenting Iñaki's acm
-K means plots (for the moment commented to not overwrite Iñaki's work)
