k5

The goal of k5 is to offer miscellaneous quality of life functions used by Kiernan Nicholls during interactive programming. They make things easier for me but are bad for scripts and packages.

Installation

You can install the development version of k5 from GitHub:

# install.packages("remotes")
remotes::install_github("kiernann/k5")

Example

library(k5)
packageVersion("k5")
#> [1] '0.0.4'

A list of frequently used packages can be loaded from a file.

load.packages(path = NULL, install = FALSE)
#> ✔ load 21 packages from
#> '/home/kiernan/R/x86_64-pc-linux-gnu-library/4.2/k5/PACKAGES'

Some functions wrap common combos like mean(x %in% y) or sum(is.na(x)).

x <- c("VT", "NH", "ZZ", "ME", NA)
prop_in(x, state.abb)
#> [1] 0.75
count_na(x)
#> [1] 1

Some functions wrap functions from other packages with different defaults.

dplyr::count(mtcars, cyl)
#>   cyl  n
#> 1   4 11
#> 2   6  7
#> 3   8 14

# sort and add fraction
k5::count2(mtcars, cyl)
#> # A tibble: 3 × 3
#>     cyl     n     p
#>   <dbl> <int> <dbl>
#> 1     8    14 0.438
#> 2     4    11 0.344
#> 3     6     7 0.219

There are also some handy shortcuts for the .Last.value tool.

df <- tail(mtcars, 50)
write_last()
#> ℹ `.Last.value` has class 'data.frame'
#> ✓ Saved tab-separated file '/tmp/RtmpFTaCH6/file15127cc7851b.tsv' (1.25K)
vc <- sample(state.name, 1000, replace = TRUE)
write_last()
#> ℹ `.Last.value` has class 'character'
#> ✓ Saved line-separated file '/tmp/RtmpFTaCH6/file151235b67c89.txt' (9.19K)
