In hodgeslab/tidycyte: Tidycyte

Description Usage Arguments Value Examples

Normalizes an individual tidycyte data frame based on a specified timem value. This function is used by normalize_by_time() to normalize pre-grouped data, and is not anticipated to be used by users.

1	timepoint_norm_group(df, t0)

`df`	A data frame of an individual tidycyte dataset. At a minimum should contain column names "value" and "elapsed".
`t0`	A numeric value specifying an individual elapsed time.

A dataframe with the value column normalized by the value where elapsed equals t0.

df %>%
  group_by(across(-c(date_time,elapsed,id,value))) %>%
  nest() %>%
  mutate(data = map(data, timepoint_norm_group, t0[[metric]])) %>%
  unnest(cols = c(data)) %>%
  ungroup()
