Is there a modulus operator in R? Anna

Does anyone know of some methods already programmed up ( ie freeware : ) ) in R for the post hoc methods in anova. Particularly Scheffe's method or Tukey's? Anna

When I am trying to put a legend on a plot where I am using "lines", R just ignores it. I can do it with boxplot or plot, but just not with lines. Am I doing something wrong? Maybe I...

I am totally confused as to how to use anova. I have three vectors and would like to use anova on them but I don't understand how lm or glm comes into play. In matlab, you just give the...

I am trying to make an array of lists. I don't think that I am doing it right however because I cannot access the individual elements of the lists once I have created the array of lists. Can someone...

Please excuse me if this is a very basic question and I am just misunderstanding the basic structure of R. Right now, I am writing everything in a buffer (emacs) and then copying it into R when it is correct...

I know how to print my own labels along the x axis: plot(1:10,xlab = "My label", axes = FALSE) axis(1,at=seq(1,10,by=2),labels=c("first","second","third","fourth","fifth")) Is there a way to...

When I am trying to use the source function to read in some lines of code, I get an error. The code is simply a boxplot: boxplot(s$fitness2weightedSum,s$OffNader10xWeightweightedSum,s$OffNader5xWeightweightedSum,main="weightedSum",col=8) axis(1,at...

I would like to do a one way anova and then a tukeyHSD. I have three vectors A,B and C. In a previous help message, I was told to do the following for the anova: y = c(A,B...

I don't know how to retain my row labels. I read in a table with row labels, ie: Price Floor Area Rooms 52. 111. 830 5 54. 128. 710 5 47.4 101 1000 4 ... but then I need...

I have two separate questions. The first is when I use xlab, the labels on my tic marks disappear. Is there a way to make them reappear? Also, is there a way to make my own labels for the tick...

I didn't explain myself well. You are right about not needing a list on the right hand side of the equation below. What I end up with is a list of arrays. Now what i would like to do...

Yes, I am using plot and then lines. The legend is just not appearing. I am using the coordinates of the legend (150,4) which work on boxplot and plot. I have not looked at the output of par (I...

I looked at the Introduction to R and am still confused. Would it be possible to ask a question in which I have three vectors and I want to perform an anova on them. Say A,B, and C. Is...

Is there a simpler way then the solution to the one that was posted here? I'm not very proficient with legend, and I don't understand this solution. All I have is two or more lines on one plot...
