...is composed of 23k rows, each one representing a point in the space of which we know the land cover over 10 years (column y01 to y10). I need to analyse it with a temporal sliding window of 5 years (y01 to y05, y02 to y06 and so forth) For each period I'm looking for specific sequences (e.g., Maize, -noMaize, -noMaize, -noMaize, -noMaize) to calculate the "return time" of principal land covers: barley (2BC), colza (2Co), maize (2Ma), etc. I define the "return time" as the presence of a given land cover according to a given sequence. Hence, each return time could require t...

You can order the shirt in one of the following colors (use the link to see the shirt in that color), but remember that the maroon logo might not look good in all these colors. Birch, Black, Gold, Jade, Kelly Green, Maize, Navy, Purple, Putty, Sports Grey, Royal Blue, White I have orders for the following people. The size ordered is as noted below. The default color is "sports grey" which will look good with the maroon logo. If you want grey and the size is correct, you needn't do anything. If not,...

Dear R Help - I am analyzing data from an ecological experiment and am having problems with the ANOVA functions I've tried thus far. The experiment consists of a blocked/split-plot design, with plant biomass as the response. The following is an overview of the treatments applied (nitrogen addition, phosphorus addition, and seeded/not seeded) and at what level (block, main-plot, and sub-plot):

Dear all, how can I perform a post hoc analysis for ANOVA with repeated measures (in presence of a balanced design)? I am not able to find a good example over internet in R...is there among you someone so kind to give me an hint with a R example please? For example, the aov result of my analysis says that there is a statistical difference between stimuli (there are 7 different stimuli). ...I

The model is > RT.aov <- aov(RT~Cond + Error(Subj/Cond), WMU3C) I understand that TukeyHSD only works with an aov object, but that RT.aov is an aovlist object. > class(RT.aov) [1] "aovlist" "listof" I've tried to work around it using the "maiz" example in the MMC documentation of the HH package (a solution previously recommended), but I couldn't get it to work: My best shot was to calculate another aov avoiding the error term (I don't see how this could be a feasible approach, but that's how I understood the MMC exam...

Is there a standardized way in R to perform post-hoc comparisons for main adn interaction effects of between- and within-subject factors? For instance, I have a data set of performance of adults of different age groups (20-30, 60-70,70-80) performing a WM task (n-back, with n=1,2,3,4) in two different conditions (while sitting or walking). The corresponding ANOVA produces the following output

Hi everyone, I'm trying to do a 2-way repeated measures ANOVA with data that looks like this: subject block rep day light response 1 1 1 one L1 5.5 2 1 2 one L1 4.5 3 1 1 one L2 4 4 1 2 one L2 5.1 5 2 1 one L1 5.3 6 2 2 one L1

Hi, I'm a bit new to R and I would like to know how can I compare simple main effects when using the aov function. I'm doing a mixed model ANOVA with two between subjects variables and one within. When I get an interaction of two of the variables I don't know how to check for simple main effect of that interaction (A at B1 and A at B2 for example). The aov function is very simple but

Hi, I did the analysis of variance of a split-plot and the effect of treatment was significant. I would like compare treatment means using Tukey.

dear all, I want to perform a posthoc test for my ANCOVA: a1<-aov(seeds~treatment*length) With summary(glht(a1, linfct = mcp(treatment = "Tukey"))) R tells me: "covariate interactions found -- please choose appropriate contrast" How do I build these contrasts? Ideally, I would like to have the posthoc test for the ANCOVA including a block-effect

Esteemed R-forum subscribers, I'm having a tough time configuring contrasts for my 3-way ANOVA. In short: I don't know how to configure (all) my contrasts correctly in order to specify (all) my comparisons of interest. I succeeded getting my contrasts of interest set up for a simpler 2-way ANOVA based on the fairly intuitive logic of the design col.names. But i'm not able to
