Coverage_data <- read.table("/home/ning/coverage.txt", header=FALSE,sep="\t",
na.strings="NA",dec=".",strip.white=TRUE)
扫描错误（file = file，what = what，sep = sep，quote = quote，dec = dec，： 项目太多了
我使用的R代码是高于。 coverage.txt是49Gb，它看起来像这样：
$ head coverage.txt
chr1 1 0
chr1 2 0
chr1 3 0
chr1 4 0
chr1 5 0
chr1 6 0
chr1 7 0
chr1 8 0
chr1 9 0
chr1 10 0
是否有人发生此错误？
