Many ways. I assume you know that Inf and -Inf are (special) numeric values that can be treated like other numerics. i.e.
> 1 == - Inf [1] FALSE So straightforward indexing (selection) would do it. But there is also ?is.infinite and ?is.finite, so apply(yourdat, 1, function(x)all(is.finite(x))) would produce the index vector to keep rows with only finite values assuming yourdat contains only numeric data. If this is not the case, just select the numeric columns to index on, i.e. apply(yourdat[sapply(yourdat,is.numeric)], 1, function(x) all(is.finite(x))) One possible problem here is handling of NA's: is.finite(c(-Inf,NA)) [1] FALSE FALSE ... so rows containing NA's but no -Inf's would also get removed. If you wish to keep rows with NA's but no -Inf's, then function(x)(is.finite(x) | is.na(x) ) could be used.
