[R] plotting groups via density and different colors

I have a data set that looks like this: dene <- data.frame(length = c(35,32,33,34,41,40,46,35,41,40,45,36,38,37,39,40,42,42,42,43,44), sex=c(1,1,1,1,2,2,2,1,2,2,2,1,2,2,2,2,2,2,2,2,2)) I would like to plot the density (frequency of occurrence) of each length class but I want to have different colo

[R] "Ghost" values after subsetting

I am using subset to select the data I want to use for my analysis and find that after I subset my data frame on one column I get ghost values in the other columns. here is an example: > table(data$Dags) 2008/04/12 2008/04/13 2008/04/16 2008/04/17 2008/04/19 2008/05/06 103

[R] ancova help

I am trying to run an ancova and am having trouble setting it up properly. I have nearly 10,000 measurements of fish length, girth and stage of sexual development. I am suspicious that the stage of development is affecting the length (as they get full of eggs they get more round and are more diffic

[R] princomp data input format

I am trying do to a PCA analysis using princomp. I get a result, but I wonder if I have the data in the correct format. My data contains many stations where fish were sampled as well as environmental information for each station (lat, lon, depth, temp and year). the format is like this: species 1|

[R] italics help in plot

Part of my script reads: speciesName <- names(data)[i] plot(year,depth, xlab="Year", ylab="Depth(m)",main=expression(italic(paste(speciesName))) ) Unfortunately, this just plots *speciesName *on my graph, not the name of the species in italics. Any suggestions on how to resolve this? Thank you J
