我有一个数据框,由两列组成:字符向量col1和list列col2.

myVector <- c("A","B","C","D")

myList <- list()
myList[[1]] <- c(1, 4, 6, 7)
myList[[2]] <- c(2, 7, 3)
myList[[3]] <- c(5, 5, 3, 9, 6)
myList[[4]] <- c(7, 9)

myDataFrame <- data.frame(row = c(1,2,3,4))

myDataFrame$col1 <- myVector
myDataFrame$col2 <- myList

myDataFrame
# row col1          col2
# 1   1    A    1, 4, 6, 7
# 2   2    B       2, 7, 3
# 3   3    C 5, 5, 3, 9, 6
# 4   4    D          7, …
