Hello,
Have you tried which=2?
dat <- readHTMLTable(readLines(Link), which = 2, header = TRUE,
na.strings = "-")
dat[, 3:15] <- lapply(dat[, 3:15], function(x) sub("([[:digit:]]) [ab]",
"\\1", x))
dat[, 3:15] <- lapply(dat[, 3:15], function(x)as.numeric(as.character(x)))
str(dat)
Hope this helps,
Rui Barradas
