as.integer(M)

eaxis
Extended / Engineering Axis for Graphics
Description
An extended axis() function which labels more prettily, in particular for log-scale axes.
It makes use of plotmath expressions of the form k × 10 k for labeling a log-scaled axis and
when otherwise exponentional formatting would be used.
Usage
eaxis(side, at = axTicks(side, log=log), labels = NULL, log = NULL,
f.smalltcl = 3/5, at.small = NULL, small.mult = NULL,
outer.at = TRUE, drop.1 = TRUE)
Arguments
side
at
labels
log
f.smalltcl
at.small
small.mult
outer.at
drop.1
integer in 1:4, specifying side of axis.
numeric vector of (“normalsized”) tick locations; by default axTicks(side),
i.e., the same as axis() would use.
NULL (default), logical, character or expression, as in axis(); in
addition, if NA, labels = TRUE is passed to axis(), i.e. pretty10exp
is not used. Use FALSE to suppress any labeling.
logical or NULL specifying if log-scale should be used; the default depends on
the current plot’s axis.
factor specifying the lengths of the small ticks in proportion to the normalsized,
labeled ticks.
locations of small ticks; default uses used as “small ticks”.
which multiples of axTicks() should be used as “small ticks” by default.
logical specifying that at.small should also be constructed outside the at
range, but still inside the corresponding par("usr").
logical specifying if "1 *" should be dropped from labels, passed to pretty10exp().
