Get length measurement accuracy in cm

Source: R/length.R
get_accuracy_cm.Rd

Derives the length measurement resolution, in centimetres, from the LngtCode column of the HL table in a DATRASraw object.

Usage

get_accuracy_cm(x)

Arguments

x

A DATRASraw object containing an HL table with a LngtCode column.

Value

A numeric scalar giving the inferred length measurement accuracy in cm.

Details

The returned value is the coarsest available resolution found in the data. If multiple length accuracies are present, the largest value is returned and a warning is issued. If unknown or missing LngtCode values are present, they are ignored when possible and a warning is issued.

The mapping from LngtCode to centimetres is:

  • "." = 0.1 cm

  • "0" = 0.5 cm

  • "1" = 1 cm

  • "2" = 2 cm

  • "5" = 5 cm

The function returns the maximum recognised length resolution present in x[["HL"]]$LngtCode, corresponding to the coarsest measurement accuracy in the data.

Examples

if (FALSE) { # \dontrun{
acc <- get_accuracy_cm(x)
} # }
