make_my_data2L: Extract random subset of a dataframe

In brouwern/compbio4all: Datasets and helpful functions for learning bioinformatics and computational biology

Description

Currently only works with data with 2-levels. Notes that if the size of the dataframe is too small to accomodate n.sample then with.rep is set to TRUE.

Usage

make_my_data2L(
  dat,
  my.code = "nlb24",
  cat.var,
  n.sample = 20,
  with.rep = FALSE
)

Arguments

dat	R dataframe to randomly subset
my.code	Unique code, such as your email address. Must contain only letters and numbers and not the at symbol or other punctuation.
cat.var	Categorical variable by which to split the data up
n.sample	Number of samples per group to randomly select. 2*n.sample will be the total size of the dataframe.
with.rep	Should sampling be with replacement? If with.rep = TRUE then individuals can occur more than once within the dataframe.

Examples

#Subset frogarms data
data(frogarms)
my.frogs <- make_my_data2L(dat = frogarms,
                           my.code = "nlb24",
                           cat.var = "sex",
                           n.sample = 20,
                           with.rep = FALSE)

summary(my.frogs)
