Calculate mean binocular pupil size

Usage

mean_gazepoint_pupil(
  master_df,
  lp_col = "LPupil",
  rp_col = "RPupil",
  output_col = "mean_pupil",
  min_eyes = 1
)

Arguments

master_df: A sample-level pupil data frame.
lp_col, rp_col: Left- and right-pupil columns.
output_col: Name of the generated column.
min_eyes: Minimum number of finite eye measurements required.

Value

The input data with a binocular mean-pupil column.

Examples

pupil <- data.frame(
  LPupil = c(3, NA, 4),
  RPupil = c(3.2, 3.5, NA)
)
mean_gazepoint_pupil(pupil)
#>   LPupil RPupil mean_pupil
#> 1      3    3.2        3.1
#> 2     NA    3.5        3.5
#> 3      4     NA        4.0
