Question

我有一个我试图在R中读取的csv文件，由于某种原因，R认为第一行是每列的标题，这是不正确的。有没有办法解决这个问题。这是我的命令：

test <- as.matrix(read.csv(file="filetable.csv", sep=",", header=FALSE))

我得到这样的东西

      AATCAGGC   X25070  
 [1,] "ACAAGGCT" " 50687"
 [2,] "ACACGATC" " 47483"
 [3,] "ACACTGAC" " 18339"
 [4,] "ACAGGAGT" " 48550"

第一行应该是数据的一部分

在记事本中打开filetable.csv我得到了这个

AATCAGGC,25070
ACAAGGCT,50687
ACACGATC,47483
ACACTGAC,18339
ACAGGAGT,48550

它的标题= FALSE而不是标题：http://stat.ethz.ch/R-manual/R-patched/library/utils/html/read.table.html

> tempFile <- tempfile()
> writeLines(c("AATCAGGC,25070",
 "ACAAGGCT,50687",
 "ACACGATC,47483",
 "ACACTGAC,18339",
 "ACAGGAGT,48550"),tempFile,sep="\n")
> readLines(tempFile)
[1] "AATCAGGC,25070" "ACAAGGCT,50687" "ACACGATC,47483" "ACACTGAC,18339" "ACAGGAGT,48550"
> as.matrix(read.csv(tempFile,sep=",",header=FALSE))
     V1         V2     
[1,] "AATCAGGC" "25070"
[2,] "ACAAGGCT" "50687"
[3,] "ACACGATC" "47483"
[4,] "ACACTGAC" "18339"
[5,] "ACAGGAGT" "48550"
