Hello, I am VERY new to R, just picking it up infact. I have got my head around the basics of ANOVA with post hoc tests but I am struggling with regression, especially with ANCOVAs.
I have two sets of data, one of type A, one of type B. Both have been placed in a wind tunnel and sampled every week. The co variate is of course the days since the start. An example is day A B 0 10.0 10.0 7 9.0 9.1 14 8.0 8.2 21 7.0 7.3 28 6.0 6.4 35 5.0 5.5 42 4.0 4.5 49 3.0 3.6 56 2.0 2.7 I have been able to do ANOVA on similar data without a co variate, everyone else seems to use ANCOVAs very different to how I do, either that or I am the only one doing something this simple. Could anyone please explain how to perform the analysis, I currently have the data in R in a data frame I have called anco. Thanks for any help.
