Exclude participants with too few trials

Removes participants who completed fewer than min_trials experiment trials, as well as any rows with a missing worker_id. This guards against partially-completed sessions being included in downstream analyses.

Usage

filter_incomplete(d, min_trials = 510)

Arguments

d

Data frame with a worker_id column.

min_trials

Integer. Minimum number of trials required for a participant to be retained. Default: 510.

Value

The input data frame with rows belonging to excluded participants (and rows with NA worker IDs) removed.

Examples

if (FALSE) { # \dontrun{
d <- data.frame(
  worker_id = c(rep("p1", 600), rep("p2", 100)),
  rt        = rnorm(700, 1500, 300)
)
filter_incomplete(d, min_trials = 510)
# only p1 is retained
} # }
