multifreqpoly {ENmix} | R Documentation |
Produce Frequency polygon plot for each column of a numeric data matrix. Similar to multidensity function, the plot can be used to inspect data distribution but with much faster speed.
multifreqpoly(mat, nbreaks=100, col=1:ncol(mat), xlab="", ylab="Frequency",legend = list(x = "top", fill=col, legend = if(is.null(colnames(mat))) paste(1:ncol(mat)) else colnames(mat)),...)
mat |
A numeric matrix |
nbreaks |
The number of bins for frequency counting |
col |
Line plot color code, the length should be equal to the number of columns in mat |
xlab |
x-axis lable |
ylab |
y-axis lable |
legend |
A list of arguments that get passed to the function "legend" |
... |
Further arguments that get passed to the function "plot" |
Frequency polygon plot.
