fold (version 0.2.6)

unfold.folded: Unfold a Folded Data.frame

Description

Unfolds a folded data.frame, or part thereof.

Usage

# S3 method for folded
unfold(x, ..., sort = TRUE)

Arguments

x

folded data.frame

...

variables to unfold, given as unquoted anonymous names

sort

whether to sort the result by groups values

Value

class 'unfolded': data.frame with a groups attribute (character)

Details

By default, the entire data.frame is unfolded, possibly giving back something originally passed to fold(). If … is specified, only selected items (given as anonymous unquoted arguments) are unfolded. Values stored as encodings are converted to factor. The result has a groups attribute: a character vector of column names in the result whose interaction makes rows unique.

Examples

# NOT RUN {
library(magrittr)
library(dplyr)
data(eventsf)
eventsf %>% unfold
eventsf %>% unfold(DV,PRED)
x <- events %>% 
  filter(CMT == 2) %>% 
  select(ID, TIME, TAD, DV, BLQ, LLOQ, SEX) 
x
attr(x,'groups') <- c('ID','TIME')

# less than 10 values of DV, so BLQ looks like an encoding
y <- x  %>% fold(meta=list(DV~BLQ,BLQ~LLOQ))
y %>% data.frame

# reducing the tolerance forces BLQ to match by groups (ID, TIME) instead of DV value
z <- x  %>% fold(meta=list(DV~BLQ,BLQ~LLOQ),tol=3)
z

# recursive unfold, since LLOQ is an attribute of BLQ, which is an attribute of DV
unfold(y)
unfold(z)
y %>% unfold(DV)
y %>% unfold(BLQ)
y %>% unfold(LLOQ)
y %>% unfold(SEX)
y %>% unfold(TAD)
y %>% unfold(DV,SEX)
y %>% unfold(TAD,SEX)
# }
