我想将 IEX 的调用转换为 R 中的数据表:
https://api.iextrading.com/1.0/ref-data/symbols
谢谢,
您可以使用fromJSON
包rjson
然后转换list
为data.frame
. 请看下面的代码:
library(rjson)
f <- (fromJSON(file = "https://api.iextrading.com/1.0/ref-data/symbols"))
df <- data.frame(t(sapply(f, unlist)), stringsAsFactors = FALSE)
str(df)
输出:
'data.frame': 8691 obs. of 6 variables:
$ symbol : chr "A" "AA" "AAAU" "AABA" ...
$ name : chr "Agilent Technologies Inc." "Alcoa Corporation" "Perth Mint Physical Gold" "Altaba Inc." ...
$ date : chr "2018-09-19" "2018-09-19" "2018-09-19" "2018-09-19" ...
$ isEnabled: chr "TRUE" "TRUE" "TRUE" "TRUE" ...
$ type : chr "cs" "cs" "N/A" "cs" ...
$ iexId : chr "2" "12042" "14924" "7653" ...
