我需要读取一个 csv 文件，它有一个标头和一个数据单元格，它是 JSON 格式的。需要读取 JSON 数据（从该单元格）并使用 R 将其转换为数据框。虽然我在网上找到了类似的问题，但我没有找到可行的解决方案。请帮忙。我尝试了下面的代码，但它没有用，不知道我在这里错过了什么。
install.packages("rjson")
library(rjson)
myData <- read.csv("sampleData.csv", nrows=1,skip = 1)
json_data_frame <- as.data.frame(myData)
dat_r = toJSON(myData)
dat_c = toJSON(myData)
dat_v = toJSON(myData)
该单元格中的数据：
