In chapmandu2/pgxsim: Simulate Dose Response Curves For Pharmacogenomics Analysis

Description

Subset a data frame and apply a function to that portion of it defined by a column named batch

Usage

subset_apply(k, df, my_fun, seed = NULL)

Arguments

k	batch id to select
df	data frame to subset
my_fun	function to apply
seed	seed value to add to batch id, makes simulations reproducible. Default is NULL, don't set seed.

Value

output of function my_fun

Examples

test_df <- data.frame(batch=1:10, x=rnorm(10))
test_df
test_fun <- function(df) {df$y <- df$x * rnorm(1); return(df)}
test_fun(test_df)
test_fun(test_df[1:3,])
subset_apply(1, test_df, test_fun)
subset_apply(1, test_df, test_fun)
subset_apply(1, test_df, test_fun, seed=1001)
