search for: eqfull

...ate data set, where I take my independent data from. I build an equation with some of the columns in data. Then I generate the generalized linear model, which works. But when I try to run the last line ? the cv.glm function, I get the following error message: Error in model.frame.default(formula = eqfull, data = list(vsurf_ID6 = c(2.4599824, : variable lengths differ (found for 'density') I fear I don't get the meaning of the error message at all. The length of the data columns are all equal. Any help would be kindly appreciated! Best wishes, Markus
