Read Pressure Data from CSV — pr_read

Reads pressure data from a CSV file in either wide (one column per sensor) or long (tidy) format.

Usage

pr_read_csv(
  path,
  format = c("wide", "long"),
  layout = NULL,
  time_col = NULL,
  sampling_hz = 100,
  verbose = TRUE
)

Arguments

path: Character. Path to CSV file.
format: Character. "wide" (default, columns are sensors) or "long" (a tidy format with frame, sensor_id, pressure).
layout: A pr_layout object. Required for wide format when the sensor count cannot be inferred.
time_col: Character. Name of the time column. If NULL, timestamps are generated from sampling_hz.
sampling_hz: Numeric. Sampling rate. Default 100.
verbose: Logical. Default TRUE.

Value

A pr_trial object.

Examples

tmp <- tempfile(fileext = ".csv")
m <- matrix(runif(10 * 99, 0, 100), nrow = 10, ncol = 99)
utils::write.csv(m, tmp, row.names = FALSE)
trial <- pr_read_csv(tmp, format = "wide", layout = pr_layout_insole(),
                     verbose = FALSE)
