R help - Jul 2014 - Model for lm keeps producing an error

Hi,



I still seem to be getting errors from trying to run my altered R script, any
advice?



Thanks

Jess



Model1A = function(meth_matrix,exposure, X1, X2, X3, batch) {
+
+   mod = lm(methcol ~ exposure+X1+X2+X3+batch, data = meth_matrix)
+
+
+   res=coef(summary(mod))[2,]
+
+
+ }
