get_subkey_value_mean: Extract (mean) values for sub-keys.

In ingonader/tskeyvalparser:

Description

Takes the (vector of) values that contain subkey-value-pairs of the (default) form: (subkey1: val1/val2/val3, subkey2: val1/val2/val3) and extracts the mean value for a specified subkey.

Usage

get_subkey_value_mean(value, subkey, key_sep = ",", keyvalue_sep = ":",
  vec_sep = "/", ...)

Arguments

value	The value extracted from the original key-value pair.
subkey	The subkey for which the data should be extracted.
key_sep	The separator that separates the subkey-value-pairs from each other. Needs to be a valid regular expression (e.g., '|' needs to be escaped as '\|')
keyvalue_sep	The separator that separates the subkey from the value(s) of that subkey. Needs to be a valid regular expression (e.g., '|' needs to be escaped as '\|')
vec_sep	The separator that separates the individual values for each subkey value. Needs to be a valid regular expression (e.g., '|' needs to be escaped as '\|')
...	parameters passed to mean function.

Value

A mean value for all values of the subkey, or NA.

Examples

#value <- get_value_text(dat_txt, key = "caliper")
#value <- value[357:360]
#subkey <- "brust-li"
dat <- c(paste0("2018-03-23; 20:30; caliper = (brust-li: 14/12/11, ",
                "brust-re: 12/13/13, bauch-li: 25/25/25, ",
                "bauch-re: 26/26/25, bein-li: 15/15/15, ",
                "bein-re: 24/23/26);"),
         paste0("2018-03-29; 19:00; weight = 90.1kg;", "2018-03-30; 21:00; ",
                "weight = 89.3kg; note = nach Laufen;"),
         paste0("2018-03-30; 21:00; caliper = (brust-li: 12/13/12, ",
                "brust-re: 12/13/13, bauch-li: 28/29/29, bauch-re: 24/21/28, ",
                "bein-li: 14/16/14, bein-re: 22/22/21);"))
