tidy_to_custom: Convert a tidy data frame to a custom QurvE format

In QurvE: Robust and User-Friendly Analysis of Growth and Fluorescence Curves

Convert a tidy data frame to a custom QurvE format

Description

This function converts a data frame in "tidy" format into the custom format used by QurvE (row format). The provided "tidy" data has columns for "Description", "Concentration", "Replicate", and "Values", with one row per time point and sample. Alternatively, the function converts data in custom QurvE column format into row format (if data.format = "col").

Usage

tidy_to_custom(df, data.format = "col")

Arguments

df	A data frame in tidy format, containing "Time", "Description", and either "Values" or "Value" columns. Optionally, meta information provided in columns "Replicate" and "Concentration" is used.
data.format	(Character string) "col" (the default) or "row". Only relevant if data is not provided in "tidy" format but has been prepared into the custom QurvE data format.

Value

A data frame in the custom format (row format) used by QurvE.

Examples

# Create a tidy data frame with two samples, five concentrations, three
# replicates, and five time points
samples <- c("Sample 1", "Sample 2")
concentrations <- c(0.1, 0.5, 1, 2, 5)
time_points <- c(1, 2, 3, 4, 5)
n_replicates <- 3

df <- expand.grid(
   Description = c("Sample 1", "Sample 2"),
   Concentration = c(0.1, 0.5, 1, 2, 5),
   Time = c(1, 2, 3, 4, 5),
   Replicate = 1:3)

df$Value <- abs(rnorm(nrow(df)))

df_formatted <- tidy_to_custom(df)
