如果我有一个2列4行数据框，例如:
structure(list(var = c("url.loc", "radius", "jt", "post.age"),
value = c("london", "25", "fulltime", "7")), row.names = c(NA,
-4L), spec = structure(list(cols = list(var = structure(list(), class = c("collector_character",
"collector")), value = structure(list(), class = c("collector_character",
"collector"))), default = structure(list(), class = c("collector_guess",
"collector")), delim = ","), class = "col_spec"), problems = <pointer: 0x60000323fee0>, class = c("spec_tbl_df",
"tbl_df", "tbl", "data.frame"))
... 如何将其转换为4个变量，使结果与以下相同:
url.loc <- "london"
radius <- "25"
jt <- "fulltime"
post.age <- "7"
我可以考虑使用assign和一个循环，但我认为有一种更优雅的方法，也许使用NSE.
谢谢
