推荐答案
如果您真的想将列名强制为R,则可以使用类似的方法:
If you really want to force the column names into R, you could use something like that:
# Data
dat <- read.csv("/path/to/data.dat", header = FALSE, skip = 1)
dat
V1 V2 V3 V4 V5
1 Test Description Test D 19700101 1.0
2 Test Description Test D 19700102 1.5
# Column names
dat.names <- readLines("/path/to/data.dat", n = 1)
names(dat) <- unlist(strsplit(gsub(">", " ", gsub("<", "", dat.names)), " "))
dat
Security Name Ticker Per Date Close
1 Test Description Test D 19700101 1.0
2 Test Description Test D 19700102 1.5
尽管我认为可能会有更好的解决方案,例如手动添加标题...
Although I think there might be better solutions, e.g. manually adding the header...
