plot.data.frame(x, labels = dimnames(data)[[2]], ...) plot.bdFrame(x, labels = names(x), ..., ask = T, nprobs = min(c(nrow(x), 500)), nbins = max(2 * nprobs, 1000))
bdFrame
to be plotted.
TRUE
, display a dialog box to confirm displaying
a new page of plots.
nprobs=min(c(nrow(x), 500))
indicates
that the maximum plotted is 500 quantiles, regardless of the size of the
data set.
nbins
bins
(getting a count for each bin).
This function is a method for the generic function
for class data.frame and class bdFrame.
It can be invoked by calling
for an
object x of the appropriate class, or directly by calling
plot.data.frame
regardless of the class of the object.
This function makes plots of the sample distributions of the variables
of a data frame. The observations of numeric predictors are graphed
by a quantile plot; that is, if
x
is a numeric variable,
sort(x)
is graphed against
ppoints(x)
. For a factor, counts
of occurrences of levels are graphed.
Note that somewhat different plots are obtained by attaching the data frame and plotting the individual variables. Try both options.
plot.bdFrame
is available only when the Big Data library is loaded.
plot(air) plot(as.bdFrame(air))
