ktools

Miscellaneous function, color palettes, collected doing modelling, many trivial ones. ## Installation

The development version from GitHub with:

devtools::install_github("kklot/ktools")

Examples of what inside:

• more: View a big object in a pager view similar to bash more, press q to quit viewing

more(LETTERS[rep(1:26, each=1000)])

• pick: wrapper of grep tp pick element with regex
• query_label: search variable labels on labelled data (e.g. haven::read_dta)

# query KAIS surveys
query_label(b1, "cmc")
#     name                              label
# 1: qhint            Date of interview (CMC)
# 2:  q102                Date of birth (CMC)
# 3:  q212 Date of birth for last child (CMC)
# 4:  q318 Date of birth for last child (CMC)

• query_name: search name on a data (e.g. haven::read_dta)

query_name(b2, "weight")                                                                                                
#          name label
# 1: rawiweight      
# 2: rawbweight      
# 3:   aiweight      
# 4:   abweight      

• facet_unwrap: unwrap a ggplot2::facet_wrap plot to view or save separately

g <- iris %>%
  ggplot(aes(Sepal.Length)) +
  geom_histogram() +
  facet_wrap(~Species)
facet_unwrap(g)

• allot: -> right assign with pipe (experimental - use interactive only)

# these two are equivalent
a <- tibble(x = 1)
tibble(x = 1) %>% allot(a)

• recode_if: like case_when when you want to keep original data (TRUE ~ original)
• rename: rename a column in data.frame
• take_note: Write a note to file
• unkount: Uncounting data frame using a weights
• surv_split to split survival time for immediate death model
• screen_to_file: write object on screen to a file, e.g. get contents of a function
• char: quoting automatic

char(a, b, c)
# [1] "a" "b" "c"

• bracket: put bracket around a text
• browse: Show data frame in browser
• cd: replicate some features of bash cd

cd()
# Moved from: /Users/knguyen/Code/R/ktools
#  to ~
cd('-')
# Moved from: /Users/knguyen
#  to /Users/knguyen/Code/R/ktools

• double_logistic: Double logistic function
• findInterval2: findInterval and return factor with label
• fractional_poly: find best fit fractional polynomial using GLM
• kut: Cut but automatically include min and max data’s value
• kompile: compile TMB with extra ktools’s C++ headers
• lsSize: list objects with size
• napply: n(amed)apply: lapply but automatic add names to output
• pfrankCopula: Frank copulas prob
• tmb_fixit: TMB fix parameters
• NullSpace penalty

nullspace_penalty()

name2list(c(x = 1, abc = 2))

Let search engines do the work of documenting.
