R重塑宽数据到长

我有以下数据框,它为跨列排列的多个标准提供了逻辑响应:

    structure(list(Householdref = c("003015002024001", "003016003006001", 
"003016004013001", "003016006002001", "003017003009002", "003017003009003", 
"003017003009004", "003017003037001", "003017003049001", "003070001026001", 
"003070003042001", "003070005002001", "003070005021001", "003070009005001", 
"003071002055001", "003071003037001", "003072003029001", "003072006002001", 
"003072006018001"), B5_Glass = c(FALSE, FALSE, FALSE, FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE), B5_Glass.bottles = c(TRUE, 
TRUE, FALSE, FALSE, TRUE, TRUE, FALSE, TRUE, FALSE, FALSE, TRUE, 
TRUE, FALSE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE), B5_Paper.cardboard = c(FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE
), B5_Metal.cans = c(TRUE, FALSE, FALSE, FALSE, TRUE, FALSE, 
FALSE, FALSE, TRUE, TRUE, TRUE, TRUE, FALSE, FALSE, TRUE, TRUE, 
TRUE, TRUE, TRUE), B5_Food.biodegradables = c(FALSE, FALSE, FALSE, 
TRUE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE), B5_Plastic.polybags = c(TRUE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE
), B5_Plastic.bottles.containers = c(FALSE, FALSE, FALSE, FALSE, 
FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, FALSE, FALSE, TRUE, FALSE, 
FALSE, TRUE, FALSE, FALSE, FALSE), B5_other = c(FALSE, FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, 
FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE)), .Names = c("Householdref", 
"B5_Glass", "B5_Glass.bottles", "B5_Paper.cardboard", "B5_Metal.cans", 
"B5_Food.biodegradables", "B5_Plastic.polybags", "B5_Plastic.bottles.containers", 
"B5_other"), row.names = c("13", "21", "25", "29", "55", "56", 
"57", "60", "61", "69", "76", "81", "83", "90", "101", "108", 
"120", "125", "127"), class = "data.frame")

我需要重新整形这些数据,以便我只有三列:Householdref, TRUE and FALSE,以便列的名称现在显示在TRUE或FALSE列中,这样每个Householdref会有多行

我一直在尝试使用reshape(),如下所示:

reshape(ar_waste_sep, direction="long", varying=2:9, sep=c("_"))

但结束了这个:

                                 Householdref                       time  B5   id
1.Glass                       003015002024001                      Glass FALSE  1
2.Glass                       003016003006001                      Glass FALSE  2
3.Glass                       003016004013001                      Glass FALSE  3
4.Glass                       003016006002001                      Glass FALSE  4
5.Glass                       003017003009002                      Glass FALSE  5
6.Glass                       003017003009003                      Glass FALSE  6
7.Glass                       003017003009004                      Glass FALSE  7
8.Glass                       003017003037001                      Glass FALSE  8
9.Glass                       003017003049001                      Glass FALSE  9
10.Glass                      003070001026001                      Glass FALSE 10
11.Glass                      003070003042001                      Glass FALSE 11
12.Glass                      003070005002001                      Glass FALSE 12

因为你不能完全看到我追求的东西。我已经搜索过高低的一个例子,它会告诉我如何做我想做的事情,并且我确定它并不是过于复杂,但我只是围成一圈。有人会知道一种快速简便的方法来达到我想要的目的,即:

  Householdref                       TRUE          FALSE
003015002024001                      Glass          NA
003015002024001                      Glass.bottles  NA
003015002024001                      NA             Paper.cardboard
003015002024001                      NA             Metal.cans
003015002024001                      NA             Plastic.bottles
003015002024001                      NA             Plastic
003017003009004                      GLass          NA
003017003009004                      NA             Glass.bottles                
003017003009004                      Paper.cardboardNA

提前感谢,

您可以使用“reshape2”中的meltdcast来获得(我认为)您想要的内容:

library(reshape2)
mydf <- melt(ar_waste_sep, id.vars="Householdref")
head(mydf)
#      Householdref variable value
# 1 003015002024001 B5_Glass FALSE
# 2 003016003006001 B5_Glass FALSE
# 3 003016004013001 B5_Glass FALSE
# 4 003016006002001 B5_Glass FALSE
# 5 003017003009002 B5_Glass FALSE
# 6 003017003009003 B5_Glass FALSE
out <- dcast(mydf, Householdref + variable ~ value, value.var="variable")
head(out)
#      Householdref               variable                  FALSE                TRUE
# 1 003015002024001               B5_Glass               B5_Glass                <NA>
# 2 003015002024001       B5_Glass.bottles                   <NA>    B5_Glass.bottles
# 3 003015002024001     B5_Paper.cardboard     B5_Paper.cardboard                <NA>
# 4 003015002024001          B5_Metal.cans                   <NA>       B5_Metal.cans
# 5 003015002024001 B5_Food.biodegradables B5_Food.biodegradables                <NA>
# 6 003015002024001    B5_Plastic.polybags                   <NA> B5_Plastic.polybags
