在读取我的 IDAT 文件时遇到问题？
setwd('C:/Users/saeed/Documents/R/win-library/4.1/minfi/extdata/')
baseDir <- system.file("extdata/", package = "minfi")
list.files(baseDir)
list.files(file.path(baseDir))
#
targets <- read.metharray.sheet(baseDir, "Book1.csv")
targets
file.path(baseDir, basename(targets$Basename))
[1] "C:/Users/saeed/Documents/R/win-library/4.1/minfi/extdata/205128000104_R01C01"

RGset <- read.metharray.exp(targets = targets)
read.metharray 中的错误（基本名称 = 文件，扩展 = 扩展，详细 = 详细，： 以下指定文件不存在：c("C:/Users/saeed/Documents/R/win-library/4.1/minfi/extdata/205128000104/205128000104_R01C01_Grn.idat, c("C:/Users/saeed/Documents/ R/win-library/4.1/minfi/extdata/205128000104/205128000104_R02C01_Grn.idat, c("C:/Users/saeed/Documents/R/win-library/4.1/minfi/extdata/205001040R02C01_Grn.idat, "C:/Users/saeed/Documents/R/win-library/4.1/minfi/extdata/205128000104/205128000104_R04C01_Grn.idat
问题似乎只出现在 R01:R04 上。
当我使用
删除前 4 列时targets.GS8 <- targets[-c(1,2,3,4),]
我能够读取 RGset。
我不确定为什么它似乎只检测到 grn_idats？
关于为什么这可能是一个问题的任何想法？ 我检查了我的目录，文件在那里，他们似乎没有检测到。
