[R] Create a function to number each repeated visit or measurements

Hi dear R list members, I am trying to create a numerical variable that tracks the visits/entries that a subject has had. For example having a database of repeated serial measurements that are ordered by subject and time. So I would get a variable that says 0 for baseline visit/measurement, 1 f

I corrected some of my syntax and changed the the glmStepAIC for glm and ti worked. I tried my command lines with the mdrr dataset (after doing the first cleaning steps as referred in the manual), the only difference is that I only took first two columns because it took too much time with one v

[R] Looking for a repeated measure two groups comparison and a two factor ANOVA in Circular distribution

Hi, I am looking for a way to study some phase data with a circular distribution measured in rad.I would like to do a two way ANOVA (if possible mixed, with inter and intrasubject).I haven´t found a package that does that in R?Does sombeody know if there is one or how to do the analysis.Thanks

Re: [R] Spatial cluster analysis of continous outcome variable

I attach the data (csv format). There are the 3 coordinates, (but as there are not so many points I wanted two do 3 analysis in each of them collapsing one variable).There are two variables to study I have posted the data as a ratio between both states and as a percentage state between both sta

[R] Spatial cluster analysis of continous outcome variable

Dear R Users, R Core Team, I have a two dimensional space where I measure a numerical value in two situations at different points. I have measured the change and I would like to test if there are areas in this 2D-space where there is a different amount of change (no change, increase, decrease).
