我有data.frame，名为“so_data”。
第13:23列是list个，它包含空单元格和单个值。如何将它们转换为数字向量？
我试过了：
matrix(unlist(rang[13:23]), ncol=11, byrow=F)
但显然我松开了所有空洞。这让一切都搞砸了。
as.data.frame(do.call(cbind, rang)))
基本上不会更改数据。
以下是数据：

编辑： 是什么造成了这个烂摊子？
上面的data.frame以12列id和11个因素开始。这些是so_data[1:12]。
调查中的排名问题产生了11个因素。像这样的东西“对于选择大学的以下11个理由中的每一个，请排列五个原因，对您来说最重要”。
然后，11个列中的每一个代表一个选择。由于只允许五个选项，因此只有五个第一列（so_data[2:6]）包含相关数据。
现在 - 对于我做一些计算和绘图，我需要稍微改变一下数据。而不是有5列代表“优先级1”，“优先级2”等，我想要11列代表一个原因。然后，每列都根据受访者为此分配的优先级来确定值。
如，
而不是：
-------------|Priority 1------- | Priority 2---| ... | Priority 5 |
respondent1 | raeason X | Reason Y | ... | reason z |
...
我想：
-------------| Reason 1 ------- | Reason 2 ---| ... | Reason 11 |
respondent1 | Priority z | Priority 2 | ... | Priority 5
...
这是一个聪明人帮助我的代码：
startcolidx = 2
endcolidx = 6
factors = unique(unlist(rang[,startcolidx:endcolidx]))
for(f in as.character(factors)) {
rang[[f]] = apply(rang, 1, function(arow) which(arow == f))
}
答案 0 :(得分：3)
您的data.frame显然已损坏：某些列是1-或0元素向量的列表 - 这不应该发生在data.frame中。 而不是试图修复它，修复生成它的代码可能更明智，更容易。
如果您坚持修复数据而不是根本问题，则可能会有以下情况：
do.call(data.frame,
lapply( so_data,
function (u) unlist(
if( is.list(u) ) lapply(u, function(v) c(v,NA)[1])
else u
)))
修改：您可以使用melt和dcast转换初始数据。
library(reshape2)
d <- so_data[1:6]
# Transform the data to a tall format:
# it is much easier to process data in tall format.
d <- melt(d, id.vars="id" )
# Transfrom the data to a wide format:
# just specify the rows and the columns on each side of ~.
# It is rarely necessary to specify value.var.
d <- dcast( d, id ~ value, value.var="variable" )
