volcanoplot {limma} | R Documentation |
Creates a volcano plot of log-fold changes versus log-odds of differential expression.
volcanoplot(fit, coef=1, highlight=0, names=fit$genes$ID, ...)
fit |
an MArrayLM fitted linear model object |
coef |
integer giving the coefficient |
highlight |
number of top genes to be highlighted |
names |
character vector giving text labels associated with the genes and to be used in highlighting |
... |
any other arguments are passed to plot |
A volcano plot is any plot which displays fold changes versus a measure of statistical significance of the change.
A plot is created on the current graphics device.
