Convierte la lista de listas al marco de datos (3)
Podemos usar tidyverse con un código más compacto y legible
library(dplyr)
library(tidyr)
library(purrr)
res1 <- mylist %>%
#bind the inner datasets and create an id column
map(bind_rows, .id = "id") %>%
#bind the outer datasets and create an EXP column
bind_rows(.id = "EXP") %>%
#reshape to wide format
spread(id, mean)
head(res1, 4)
# EXP year EM-V6 R0-R4 R4-R9 V6-R0
#1 exp1.1 2011 34 31 27 30
#2 exp1.1 2012 34 32 29 33
#3 exp1.1 2013 32 32 28 33
#4 exp1.1 2014 28 33 28 32
O podemos abordar esto haciendo un bucle a través de la lista mylist con lapply , luego crearemos una nueva columna ''nombre'', asignaremos el Map cbind los names de los elementos de la list interna, luego rbind los elementos de la list con do.call(rbind , ahora hagamos un segundo Map para crear una nueva columna basada en los names de ''mi lista'', rbind los elementos de la list y luego reshape desde la base R para convertirla en ''amplia''
res <- do.call(rbind, Map(cbind, lapply(mylist, function(x)
do.call(rbind, Map(cbind, x, name = names(x)))), EXP= names(mylist)))
res2 <- reshape(res, idvar = c("year", "EXP"),
timevar = "name", direction = "wide")
row.names(res2) <- NULL
head(res2, 4)
# year EXP mean.EM-V6 mean.V6-R0 mean.R0-R4 mean.R4-R9
#1 2011 exp1.1 34 30 31 27
#2 2012 exp1.1 34 33 32 29
#3 2013 exp1.1 32 33 32 28
#4 2014 exp1.1 28 32 33 28
NOTA: No se usaron paquetes externos (100% base R )
o use dcast de reshape2 para transformarlo a formato ''ancho''
library(reshape2)
res2 <- dcast(res, year + EXP~name, value.var = "mean")
head(res2, 4)
# year EXP EM-V6 V6-R0 R0-R4 R4-R9

mylist una lista anidada, llamada mylist que tiene una longitud de 4.
Cada elemento de esta lista es un experimento: exp1.1 , exp1.2 , exp2.1 y exp2.2 .
Cada experimento contiene observaciones de la duración (en días) de cuatro etapas de crecimiento de la planta: EM-V6 V6-R0 R0-R4 y R4-R9 .
Cada etapa de crecimiento está organizada como un marco de datos con el year y la mean .
Aquí está la información completa:

Lo que significa:
- first year, first experiment, and growth stages.
- first year, second experiment and growth stages.
- first year, third experiment and growth stages
- first year, fourth experiment and growth stages
- second year, first experiment and growth stages
y así.
¿Cómo realizar esa transformación de datos?
Tidyverse alternativo:
library(tidyverse)
map_df(mylist, ~bind_rows(., .id="id"), .id="EXP") %>%
spread(id, mean)
Una alternativa que usa rbindlist del data.table dos veces:
library(data.table)
# bind the dataframes in the ''listed lists'' together and include the year with the ''id''-parameter
# the resulting ''data.table''s are returned as a list
step1 <- lapply(mylist, rbindlist, id = ''stages'')
# bind the resulting list together and include the experiment id
step2 <- rbindlist(step1, id = ''experiment'')
# reshape to wide format
dcast(step2, year + experiment ~ stages, value.var = ''mean'')
O de una vez:
dcast(rbindlist(lapply(mylist, rbindlist, id = ''stages''), id = ''experiment''),
year + experiment ~ stages, value.var = ''mean'')
lo que da:
year experiment EM-V6 R0-R4 R4-R9 V6-R0
