Generate a plot of log fold change versus mean expression (MA plot)
## S4 method for signature 'data.frame' plotMA( object, ylim = NULL, colNonSig = "gray32", colSig = "red3", colLine = "#ff000080", log = "x", cex=0.45, xlab="mean expression", ylab="log fold change", ... )
object |
A |
ylim |
The limits for the y-axis. If missing, an attempt is made to choose a sensible value. Dots exceeding the limits will be displayed as triangles at the limits, pointing outwards. |
colNonSig |
colour to use for non-significant data points. |
colSig |
colour to use for significant data points. |
colLine |
colour to use for the horizontal (y=0) line. |
log |
which axis/axes should be logarithmic; will be passed to |
cex |
The |
xlab |
The x-axis label. |
ylab |
The y-axis label. |
... |
Further parameters to be passed through to |
plotMA( data.frame( `M` = exp(rexp(1000)), `A` = rnorm(1000) -> tmp, `isde` = abs(tmp)>2) )
