Expression List

Description

Add a new expression to a list (of expressions).

Usage

add_expr(expr_ls, new_expr)

Arguments

expr_ls	(list of call) the list to which a new expression should be added.
new_expr	(call) the new expression to add.

Details

Offers a stricter control to add new expressions to an existing list. The list of expressions can be later used to generate a pipeline, for instance with pipe_expr.

Value

a list of call.

Examples

library(rtables)

lyt <- list()
lyt <- add_expr(lyt, substitute(basic_table()))
lyt <- add_expr(
  lyt, substitute(split_cols_by(var = arm), env = list(armcd = "ARMCD"))
)
lyt <- add_expr(
  lyt,
  substitute(
    test_proportion_diff(
      vars = "rsp", method = "cmh", variables = list(strata = "strata")
    )
  )
)
lyt <- add_expr(lyt, quote(build_table(df = dta)))
pipe_expr(lyt)
