Description

Create a row records to block records transform specification object that holds the pivot control table, specification of extra row keys, and control table keys.

Usage

rowrecs_to_blocks_spec(
  controlTable,
  ...,
  recordKeys = character(0),
  controlTableKeys = colnames(controlTable)[[1]],
  checkNames = TRUE,
  checkKeys = FALSE,
  strict = FALSE,
  allow_rqdatatable = FALSE
)

Arguments

controlTable

an all character data frame or cdata pivot control.

...

not used, force later arguments to bind by name.

recordKeys

vector of columns identifying records.

controlTableKeys

vector of keying columns of the controlTable.

checkNames

passed to rowrecs_to_blocks.

checkKeys

passed to rowrecs_to_blocks.

strict

passed to rowrecs_to_blocks.

allow_rqdatatable

logical, if TRUE allow rqdatatable shortcutting on simple conversions.

Value

a record specification object

Examples


d <- wrapr::build_frame(
  "id"  , "AUC", "R2" |
    1   , 0.7  , 0.4  |
    2   , 0.8  , 0.5  )

transform <- rowrecs_to_blocks_spec(
  wrapr::qchar_frame(
    "measure", "value" |
    "AUC"    , AUC     |
    "R2"     , R2      ),
  recordKeys = "id")

print(transform)

d %.>% transform

inv_transform <- t(transform)
print(inv_transform)

# identity (in structure)
d %.>% transform %.>% inv_transform

# identity again (using .() "immediate" notation)
d %.>% transform %.>% .(t(transform))
