Vectorized Colors for plotting XChromatogram September 09, 2019, 04:41:02 AM Dear Develops,would it be possible for the plotting functions such as:## XChromatograms {xcms}## S4 method for signature 'XChromatogram,ANY'## plot(x, col = "#00000060", lty = 1, type = "l", xlab = "retention time", ylab = "intensity", main = NULL, peakType = c("polygon", "point", "rectangle", "none"), peakCol = "#00000060", peakBg = "#00000020", peakPch = 1, ...)## plotChromPeakDensity,XCMSnExp-method {xcms} ## S4 method for signature 'XChromatograms'##plotChromPeakDensity(object, param, col = "#00000060", xlab = "retention time", main = NULL, peakType = c("polygon", "point", "rectangle", "none"), peakCol = "#00000060", peakBg = "#00000020", peakPch = 1, simulate = TRUE, ...)to have the arguments:peakCol = "#00000060", peakBg = "#00000020" (maybe also peakPch = 1) to be able to take vectorized colors like in the argument col?This would enable mor freedom whilst plotting.kind regardsTony[attachment deleted by admin] 1 Likes
Re: Vectorized Colors for plotting XChromatogram Reply #1 – September 09, 2019, 07:21:14 AM Hi Tony,excellent suggestion! The parameters are however already vectorized. peakCol, peakBg and peakPch can be either of length 1 or length equal to the number of peaks the XChromatogram/XChromatograms object has peaks (i.e. nrow(chromPeaks(x)) with x being a XChromatogram or an XChromatograms object). You can then define the color for each individual peak (the order of the colors passed along has to match the order of the peaks returned by chromPeaks.cheers, jo
