My thanks to this mailing list and its members for their great help in the past. I have yet another question per the following code and comments:
# I need individual graphs grouped by "PARLABEL" AND "Event", with "PARLABEL" # controlling pct and lty, and "Event" controlling col (where Event==1 is green # and Event==2 is red). This is attempted in the xyplot parameter # "groups = c(PARLABEL, Event)". Current behavior appears to be that the # colors are controlled by "PARLABEL" along with the shape and line type. Some # experimentation with those two parameters (reverse order, one or the other only) # suggests that the second parameter is ignored. # # I have also experimented with panel.superpose, subsetting, and Extended formula # interface, as appears to be suggested by the "man pages", but to no avail. # # Note that I can get the graphics layout I need with ggplot2, but that has its # own issues with secondary axis and subtitle text placement, formatting, and # pagination. # # Example script below. Datafile included. depthlimit=c(7,-1) xlimit=c(0.1,125000) TransectOrder = c("LLR19", "LLR18", "LLR17") OffsetOrder = c("T", "U", "V", "Y", "Z", "A", "B", "C", "D", "E", "F", "G", "H") # Parse the data for these plots --------------------------------------------- df <- read.csv(file = "5.04-r02_LTC-SE-SO-Compared.csv") df$Transect <- factor(df$Transect, levels = TransectOrder) levels(df$Transect) df$Offset <- factor(df$Offset, levels = OffsetOrder) levels(df$Offset) xyplot((sbd+sed)/2 ~ Result | Offset+Transect, groups = c(PARLABEL, Event), as.table = TRUE, drop.unused.levels = FALSE, data = df, layout = c(13,3), type = "b", xlim = c(0.01, 122000), ylim = depthlimit, pch =c(16, 18), cex = c(1, 1), # to be controlled by "PARLABEL" lty =c("dashed", "solid"), # to be controlled by "PARLABEL" col = c("green", "red"), # to be controlled by "Event" scales = list(alternating = 1, x = list(rot = 45, log = TRUE))) Yours, Guy Jett, R.G.
