When replicating "main.R" that compute and create a recurrence plot for the Lorenz systems ( commit d3c304e ), the script located at https://github.com/mxochicale-phd/thesis/blob/master/0_code_data/1_code/4_figs_ch3/fig_3.5/code/main.R got the following error:

> source(paste(getwd(),"/main.R", sep=""), echo=TRUE)
> saveRP(filename_extension,width,height,rplot)
