PlotTCs function

Plot multiple time-course expression patterns for one gene

A plotting function that generates a line plot for a single gene in multiple time-course expression sets. Each time-course is overlaid on the same plot.

PlotTCs(TClst, tgene, main = "", scale = TRUE, xlab = "Time", 
    ylab = "", xAxsLabs = colnames(TClst[[1]]), ledgeX = "top", 
    colAdj = 0.4, tcols = c("red", "red", "blue", "blue"), tltys = c(1, 1, 2, 2))

Arguments

• TClst: A named list of time-course matrices. Each element of the list is a time-course expression matrix (Genes as rows and time points as columns).
• tgene: A string of a single gene accession (found in the row names of one element of TClst).
• main: Main figure title.
• scale: Logical: should the expression values of each time-course be scaled and centered?
• xlab: The X-axis label.
• ylab: The Y-axis label.
• xAxsLabs: A vector of names to be associated with each x-axis point.
• ledgeX: The x value from legend function. Determines where the legend is plotted.
• colAdj: Controls the alpha channel for the line colors using adjustcolor.
• tcols: A vector of colors controlling the colors of the lines. Must list one color for each time-course in TClst.
• tltys: A vector of integers controlling the line type (lty) of the lines. Must list one lty for each time-course in TClst.

Details

This function is used to view the expression pattern of a single gene across multiple time-course samples.

Returns

The function generates a plot with multiple lines.
