Tests ... of what?
Perhaps you should learn to search:
install.packages('sos')
library(sos)
findFn("Tarone-Ware")
The 'comp' function in {survMisc} package promises several log-rank
tests, one of them named Tarone-Ware, another named Gehan-Breslow. It would
probably help to refer to the section of Klein J, Moeschberger M 2003 Survival
Analysis, 2nd edition, that is cited on the help page. These test are described
in terms of Fleming-Harrington weights and Klein and Moeschberger has several
pages describing this family of tests.

Do you meant the (cumulative) hazard function that is 1 minus the survival
function? (And you should not capitalize the name of the 'survival'
package.)
