prop | R Documentation |
Compute proportions, percents, or counts for a single level

perc(x, data = parent.frame(), ..., format = "percent")
x |
an R object, usually a formula |
data |
a data frame in which |
useNA |
an indication of how NA's should be handled. By default, they are ignored. |
... |
arguments passed through to |
success |
the level for which counts, proportions or percents are calculated |
level |
Deprecated. Use |
long.names |
a logical indicating whether long names should be when there is a conditioning variable |
sep |
a character used to separate portions of long names |
format |
one of |
quiet |
a logical indicating whether messages regarding the success level should be supressed. |
pval.adjust |
a logical indicating whether the "p-value" adjustment should be applied. This adjustment adds 1 to the numerator and denominator counts. |
prop1
is intended for the computation of p-values from randomization
distributions and differs from prop
only in its default value of
pval.adjust
.
For 0-1 data, success
is set to 1 by default since that a standard
coding scheme for success and failure.
if (require(mosaicData)) {
prop( ~sex, data=HELPrct)
prop( ~sex, data=HELPrct, success = "male")
count( ~sex | substance, data=HELPrct)
prop( ~sex | substance, data=HELPrct)
perc( ~sex | substance, data=HELPrct)
}
