I do not fully understand your example but if you need to act on the columns of a dataframe why don't you just call its columns the title you want. something like
X<-matrix(rnorm(1000), ncol=4)
colnames(X)<-c("foo", "foo1", "foo2", "foo3") X<-as.data.frame(X)
par(mfrow=c(2,2))
lapply(colnames(X), function(x) plot(X[,x], ylab="y", xlab="x", main=x))
