read_ciras4 {gasanalyzer}

Reads CIRAS-4 csv files and creates a tibble with gas-exchange data

Description

The csv files stored by the CIRAS-4 contain measured and calculated values that are read by this function and formatted in a large tibble for use with R. Note that no recalculation of derived variables are performed, although it is possible to do so using recalculate() after importing the data.

Usage

read_ciras4(filename)

Arguments

filename

a csv file containing gas-exchange data.

Details

Multiple files can be loaded by calling the function with lapply() or purrr::map() to merge multiple files. In this case, it is important to ensure that the column names will match.

Value

a tibble with gas-exchange data in columns.

Examples

example <- system.file("extdata", "ciras4.csv", package = "gasanalyzer")

# Read using unified column names:
cir4 <- read_ciras4(example)

# Recalculate data using default gas exchange equations:
cir4_recalc <- recalculate(cir4, create_equations(c("default", "ciras4")))

# View differences:
all.equal(cir4, cir4_recalc[names(cir4)], tol = 0.001)
