我有一个包含以下变量的数据框:
id<- c('A', 'B', 'C', 'll')
location<- list(c('newyork', 'boston'), c('london','paris'), NULL, c('mumbai'))
df<- data.frame(id, location)
write.csv(df, file='test.csv')
我想从数据框创建一个csv文件,但由于该位置是一个列表,我收到错误?关于我如何在R中做到这一点的任何想法?
这种事物数据结构是预期的,如果csv不允许嵌套结构,它可能会有问题。 xls或xlsx怎么样?
id location
A c(newyork, boston)
B c(london, paris)
C Null
D c('mumbai')
答案 0 :(得分:2)
运行paste
以合并location
中的元素。然后一切都可以是一样的。
id<- c('A', 'B', 'C', 'll')
location<- list(c('newyork', 'boston'), c('london','paris'), NULL, c('mumbai'))
location = paste(location,sep = "")
df = data.frame(id,location)
write.csv(df, file='test.csv')
#> df
# id location
#1 A c("newyork", "boston")
#2 B c("london", "paris")
#3 C NULL
#4 ll mumbai
csv
如下所示:
"","id","location"
"1","A","c(""newyork"", ""boston"")"
"2","B","c(""london"", ""paris"")"
"3","C","NULL"
"4","ll","mumbai"
如果需要,可以进一步清理
