plot.mgram {ecodist} | R Documentation |
Plot a Mantel correlogram from an object of S3 class mgram
, using solid symbols for significant values.
## S3 method for class 'mgram': plot(x, pval = 0.05, xlab = "Distance", ylab = "Mantel r", ...)
x |
an object of class mgram |
pval |
cut-off level for statistical significance. |
xlab |
x-axis label. |
ylab |
y-axis label. |
... |
optional, any additional graphics parameters. |
draws a plot (graphics device must be active).
