我一直在尝试
> loc.dat[1:2,1:3]
imageNumber.1 imageNumber.2 imageNumber.3
1 latitude=34.73388 latitude=34.73393 latitude=34.7339966667
2 longitude=-106.7133033333 longitude=-106.7128583333 longitude=-106.7123566667
但由于
，这不起作用df <- unlist(strsplit(loc.dat, '=', fixed=TRUE))[2]
我尝试了lapply和for循环，但它不起作用。我确信它很简单，但我以前没遇到过这个问题。
有没有人有更好的解决方案？
答案 0 :(得分：1)
strsplit无法直接应用于数据框。您可以使用lapply循环遍历列。以下是来自lapply的{{1}}和tstrsplit的方法，假设所有列都是字符类而不是因子：
data.table
