The prettyunits package formats quantities in human
readable form. * Time intervals: ‘1337000’ -> ‘15d 11h 23m 20s’. *
Vague time intervals: ‘2674000’ -> ‘about a month ago’. * Bytes:
‘1337’ -> ‘1.34 kB’. * Rounding: ‘99’ with 3 significant digits ->
‘99.0’ * p-values: ‘0.00001’ -> ‘<0.0001’. * Colors: ‘#FF0000’
-> ‘red’. * Quantities: ‘1239437’ -> ‘1.24 M’.
You can install the package from CRAN:
install.packages("prettyunits")pretty_bytes formats number of bytes in a human readable
way:

command, with nicely formatted file sizes:
uls <- function(path = ".") {
files <- dir(path)
info <- files %>%
lapply(file.info) %>%
do.call(what = rbind)
info$size <- pretty_bytes(info$size)
df <- data.frame(d = ifelse(info$isdir, "d", " "),
mode = as.character(info$mode), user = info$uname, group = info$grname,
size = ifelse(info$isdir, "", info$size), modified = info$mtime, name = files)
print(df, row.names = FALSE)
}

in a human readable way:

pretty_sec does the same for seconds, and
pretty_dt for difftime objects. The optional
compact argument turns on a compact, approximate
format.

intervals using a vague format, omitting smaller units. They both have
three formats: default, short and
terse. vague_dt takes a difftime
object, and time_ago works relatively to the specified
date.
