Hello All,
This works,
results<- read.table("plink.txt",T)
while this doesn't.
results<- read.table("plink.txt")
Make sure your data frame contains columns CHR, BP, and P
What does adding the "T" in read.table do? Which argument does this
correspond to? I tried searching for it but didn't find the answer in:
read.table(file, header = FALSE, sep = "", quote = "\"'",
dec = ".", row.names, col.names,
as.is = !stringsAsFactors,
na.strings = "NA", colClasses = NA, nrows = -1,
skip = 0, check.names = TRUE, fill = !blank.lines.skip,
strip.white = FALSE, blank.lines.skip = TRUE,
comment.char = "#",
allowEscapes = FALSE, flush = FALSE,
stringsAsFactors = default.stringsAsFactors(),
fileEncoding = "", encoding = "unknown")
Could someone please explain?
You didn't name your arguments, so positional matching is used. Your call is equivalent to read.table(file = "plink.txt", header = T) In most users' sessions, that's the same as read.table(file = "plink.txt", header = TRUE) and I'd guess that's true about yours. Duncan Murdoch
