Dear All, I am fitting a simple GAM model using the "gam" function in the "mgcv" package. The only independent variable is a continuous variable representing the time of the event (in year and month) coded so that "0" represents January 1960, "1" represents February 1960, etc. Now when I try to plot the results, my x-axis ranges from "-200" to "200", what I want is to convert these number into something like "1950-01" or "Jan. 1950". What is the best way to do this? Many thanks. Best, Shige
How about decimal years? ?Would that suffice? yourdates <- -200:200 dec.year <- 1960 + yourdates/12 Jean
