psrank-deprecated: Calculation of Pseudo-Ranks (Deprecated)

In happma/pseudorank: Pseudo-Ranks

Calculation of Pseudo-Ranks (Deprecated)

Description

Calculation of (mid) pseudo-ranks of a sample. In case of ties (i.e. equal values), the average of min pseudo-ranks and max-pseudo-ranks are taken (similar to rank with ties.method="average").

Usage

psrank(x, ...)

Arguments

x	vector containing the observations
...	further arguments (see help for pseudorank)

Value

Returns a numerical vector containing the pseudo-ranks.

Examples

df <- data.frame(data = round(rnorm(100)), group = c(rep(1,40),rep(2,40),rep(3,20)))
df$group <- as.factor(df$group)

## two ways to calculate pseudo-ranks

# Variant 1: use a vector for the data and a group vector
pseudorank(df$data,df$group)

# Variant 2: use a formula object, Note that only one group factor can be used
# that is, in data~group*group2 only 'group' will be used
pseudorank(data~group,df)
