If you haven't done so you *must* read an Introduction to R. The only
reason this is a problem is Myarray is a character string, not a function
or expression to be evaluated. I think this will get you what you want
though:

# In the future use the output of ?dput to provide data to this list
 (MyMatrix <- structure(c(10, 20, 30, 40, 50, 60, 70, 80, 90), .Dim = c(3L,
3L), .Dimnames = list(NULL, c("ABC", "PQR", "XYZ"))))

# DO NOT use rich font !!! in plain text it adds '*' to the bold names
which is more than annoying...
MyArray <-  c("ABC>50","PQR<50","ABC<30 & XYZ<40")

# finally the answer:
sapply(MyArray,function(x) eval(parse(text=x),as.data.frame(MyMatrix)))
