R help - Jul 2014 - lm and 450k data

Hi,



I'm quite new to R and currently trying to use lm to fit linear models but I
am currently stuck my code is as follows:



Model1 = function(meth_matrix,exposure, X1, X2, X3, batch) {

  mod = lm(meth_matrix[, methcol]~exposure+X1+X2+X3+batch)

  res = summary(mod)$coef[2,]



system.time(indiv.results <-  mclapply(setNames(ncol=473864(cord_betas)),
dimnames(cord_betas)[[2]]), Model1, meth_matrix=cord_betas,
exposure=filtered_pheno, X1=covariates$k032, X2=covariates$k021,
X3=covariates$kz029, batch=pdata.B1221.cord$BCDPlate))


}



I am not sure if this will make any sense or if you need any more information?

Any help or guidance would be massively appreciated.



Best wishes
