Compute row-wise mean across observer columns

For each entry in prefixes, finds matching columns and appends a new column to d containing the row-wise mean, ignoring NAs.

Usage

addObserverMeans(
  d,
  prefixes = list(SNR = "snr_observer", noiseRMSdB = "noiseRMSdB_observer", signalRMSdB =
    "signalRMSdB_observer")
)

Arguments

d

A data frame containing observer metric columns.

prefixes

A named list or named character vector where names become the new column names and values are either a single string pattern or a character vector of explicit column names. Defaults to list(SNR = "snr_observer", noiseRMSdB = "noiseRMSdB_observer", signalRMSdB = "signalRMSdB_observer").

Value

The input data frame d with one additional column per entry in prefixes.

Examples

if (FALSE) { # \dontrun{
# Default: pattern-based
d <- addObserverMeans(d)

# Mixed: pattern-based and explicit
d <- addObserverMeans(d, prefixes = list(
  SNR        = "snr_observer",
  noiseRMSdB = c("noiseRMSdB_observer1", "noiseRMSdB_observer2")
))
} # }
