[R] Plotting an interaction with error bars

Hello. I need to plot a two-way interaction (5 levels X 3) with error bars. The x.factor will be the five-levels var and the trace.factor will be the three level var. I was able to find functions that draw error bars, but still couldn't find a way to draw an interaction plot that looks like what

[R] Plotting power function to practice data

Hello, I have practice data of motor action in the format: S | Cond. | Time +-+ 01 | c | 1.23 01 | nc| 0.89 02 | c | 2.15 02 | nc| 1.80 . I want to look at the learning curves graphically. I will appreciate pointers to relevant functions / pack

[R] Structure of Anova for obtaining sig. corrected for departure from sphericity

Dear helpers, I have a 2x2 mixed design with two "groups" (between-subjects) and two presentation-types (within-subjects). The difference between groups is in the order of manipulations: group.CD having first a block of present.type.C and then a block of present.type.D, each block containing 31 t

[R] Doing a mixed-ANOVA after accounting for a covariate

Dear r helpers, I would like to look at the interaction between two two-level factors, one between and one within participants, after accounting for any variance due to practice (31 trials in each of two blocks) in the task. It seems to require treating practice as a covariate. All the examples I
