Examples

# "4+/TNFa+" and "4+/IL2+" are two existing gates
#note: no spaces between node names and & , ! operators
booleanFilter(`4+/TNFa+&!4+/IL2+`)
#> booleanFilter filter '4+/TNFa+&!4+/IL2+' evaluating the expression:
#> 4+/TNFa+&!4+/IL2+

#programmatically 
n1 <- "4+/TNFa+"
n2 <- "4+/IL2+"
exprs <- paste0(n1, "&!", n2)
call <- substitute(booleanFilter(v), list(v = as.symbol(exprs)))
eval(call)
#> booleanFilter filter '4+/TNFa+&!4+/IL2+' evaluating the expression:
#> 4+/TNFa+&!4+/IL2+
