Some of the main functions of this package are:

Pipe %||% evaluates nullity between two objects and:
1. return x if neither x nor y is NULL, empty or NA
2. return x if y is NULL, empty or NA
3. return y if x is NULL, empty or NA

library(dstools)

# **return x** if neither x nor y is NULL, empty or NA
x <- "pepe"
y <- "x"

x %||% y
#> [1] "pepe"

# **return x** if y is NULL, empty or NA
x <- "pepe"
y <- NULL

x %||% y
#> [1] "pepe"

# return y if x is NULL, empty or NA
x <- NULL
y <- "x"

x %||% y
#> [1] "x"

remove_accents eliminates accents from vocals and return the given string value without them

remove_accents("Thís accénts áré góing to bé removéd")
#> [1] "This accents are going to be removed"

is.empty evaluates object emptiness

# Empty object
empty_object <- list()
is.empty(empty_object)
#> [1] TRUE

# Not empty object
non_empty_object <- "hello"
is.empty(non_empty_object)
#> [1] FALSE

na_to_chr replace NA values with a given value

sample <- c("text 1", NA, "text 2", "text 3", NA)

na_to_chr(sample, "ex_na")
#> [1] "text 1" "ex_na"  "text 2" "text 3" "ex_na"

na_proportion estimates the proportion of NA values in a vector

sample <- c(NA, NA, 1,2,3,4)
na_proportion(sample)
#> [1] 0.3333333
