这是怎么回事?

这里是用来获取上表中的代码:
library(stringr)
# Open Connection to file
pathToFile <- path.expand("~/path/to/file/myfile.txt")
f <- file(pathToFile, "rb")
# Read in lines
rawText <- readLines(f)
# Find the dahses
dsh <- str_locate_all(rawText, " - ")
# Splice, using the dashes as a guide
lng <- length(rawText)
spliced <- sapply(1:lng, function(i)
spliceOnDash(rawText[[i]], dsh[[c(i, 1)]], dsh[[c(i, 2)]])
)
# make it purtty
nicelyFormatted <- formatNicely(spliced)

# return
c(unlist(pre), unlist(dates), unlist(post))

# Function to clean up the list into a nice table
formatNicely <- function(spliced) {
lngst <- max(sapply(spliced, length))

在哪里,这些数据从何而来?原始文件中是否有可用的制表符分隔符? – mnel
是的,在变量的两个名称之间的每个变量和空格之间都有制表符分隔符。这些只是团队统计数据,每一列应该代表一个变量(9个变量)。我无法弄清楚,因为这个数据集包含字符串,数字和日期变量。任何帮助将不胜感激。 –
然后使用'read.table(thedatafile,sep ='\ t')'。你可以发布'dput(test)'的结果(在你重新分配strsplit之前),我可以发布一个有用的答案。 – mnel
