replyr (version 0.8.2)

replyr_summary: Compute usable summary of columns of tbl.

Description

Compute per-column summaries and return as a data.frame. Warning: can be an expensive operation.

Usage

replyr_summary(x, ..., countUniqueNum = FALSE, countUniqueNonNum = FALSE,
  cols = NULL)

Arguments

x

tbl or item that can be coerced into such.

...

force additional arguments to be bound by name.

countUniqueNum

logical, if true include unique non-NA counts for numeric cols.

countUniqueNonNum

logical, if true include unique non-NA counts for non-numeric cols.

cols

if not NULL set of columns to restrict to.

Value

summary of columns.

Details

Can be slow compared to dplyr::summarize_all() (but serves a different purpose). Also, for numeric columns includes NaN in nna count (as is typcial for R, e.g., is.na(NaN)). And note: replyr_summary() currently skips "raw" columns.

Examples

# NOT RUN {
d <- data.frame(p= c(TRUE, FALSE, NA),
                r= I(list(1,2,3)),
                s= NA,
                t= as.raw(3:5),
                w= 1:3,
                x= c(NA,2,3),
                y= factor(c(3,5,NA)),
                z= c('a',NA,'z'),
                stringsAsFactors=FALSE)
d$q <- list(1,2,3)
replyr_summary(d)

# }
