Error: "Columns of type list not supported yet" in R when trying to write dta file using the haven package

Question

我的三个专栏表现得很奇怪，即使它们在我的数据框中被声明为 numeric。我也无法使用 colnames

更改这些列的名称

我的步数：

install.packages("避风港")
图书馆（天堂）
write_dta(data = df, "path/mydata.dta")

我的数据框df

structure(list(WeekDaysAbove28 = structure(list(`tapply(testdlong$value > 28, ceiling(seq(nrow(testdlong))/7), ` = c(0L, 
0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 
0L, 0L, 0L)), row.names = c("1", "2", "3", "4", "5", "6", "7", 
"8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", 
"19", "20"), class = "data.frame"), WDA28 = structure(list(`tapply(testdlong$value > 28, ceiling(seq(nrow(testdlong))/7), ` = c(0L, 
0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 
0L, 0L, 0L)), row.names = c("1", "2", "3", "4", "5", "6", "7", 
"8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", 
"19", "20"), class = "data.frame"), WDBM5 = structure(list(`tapply(testdlong$value < -5, ceiling(seq(nrow(testdlong))/7), ` = c(0L, 
0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 
0L, 0L, 0L)), row.names = c("1", "2", "3", "4", "5", "6", "7", 
"8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", 
"19", "20"), class = "data.frame")), row.names = c(NA, 20L), class = "data.frame")

错误 “尚不支持类型列表的列” 建议我需要以某种方式更改这些列中给出的信息，但我无法弄清楚到底出了什么问题。我有 294 列，当这三列被排除在外时，write_dta 命令工作正常

Answer 1

您有嵌套数据框。这很可能是因为您运行上一步（使用 tapply）不正确。试试这个：

result <- data.frame(lapply(df, `[[`, 1))
result

#   WeekDaysAbove28 WDA28 WDBM5
#1                0     0     0
#2                0     0     0
#3                0     0     0
#4                0     0     0
#5                0     0     0
#6                0     0     0
#7                0     0     0
#8                0     0     0
#9                0     0     0
#10               0     0     0
#11               0     0     0
#12               0     0     0
#13               0     0     0
#14               0     0     0
#15               0     0     0
#16               0     0     0
#17               0     0     0
#18               0     0     0
#19               0     0     0
#20               0     0     0

str(result)
#'data.frame':  20 obs. of  3 variables:
# $ WeekDaysAbove28: int  0 0 0 0 0 0 0 0 0 0 ...
# $ WDA28          : int  0 0 0 0 0 0 0 0 0 0 ...
# $ WDBM5          : int  0 0 0 0 0 0 0 0 0 0 ...

我们可以使用

library(purrr)
map_dfr(df, pluck, 1)
