Hello, I want to arrange data from a table to perform a simple regression. All the examples I saw deal with paired data, e.g. 'x' and 'y' have the same dimensions (e.g. 5 values for x and 5 for y).
But I have more than one 'y' for each 'x' value, e.g. the data file has a x = 0, 30, 60, and 120 columns. And for each of them I have several replicate responses (e.g. individuals), not allways the same number. After I read the data with read.table(), ending with 4 columns, what is next? how can I regress this against c(0, 30, 60, 120)? 0 --> n1 y values 30 --> n2 y values 60 --> n3 y values 120 --> n4 y values Thanks, Tomas ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
