Hello, writing some R code to cleanse a data set, if the following set
of symbols are identified then perform some actions. trying to write
the minimum code to do this.
tname = "VIX"
checkticker = c("VIX", "TYX", "TNX",
"IRX")
if (tname == checkticker) {
//perform some operations
}
result i get is
> tname == checkticker
[1] TRUE FALSE FALSE FALSE
how do i evaluate this whole list to a single boolean True or False? If
any of these are true the whole statement is True, else False. this
only seems to work for the first ticker, the rest don't perform the
operations within the loop.

[R] evaluate a set of symbols within an IF statement
Hi zubin,
Try also
tname = "VIX"
checkticker = c("VIX", "TYX", "TNX",
"IRX")
is.element(tname, checkticker)
# [1] TRUE
HTH,
Jorge
