Lida, I expect that there is a better way to solve your problem than the process you propose.
However, something like this may do what you want. ### ## met <- read.csv("your_met_file”) ## Since I do not have your file a made a small 5*1 character vector. met <- c("glycine_imp", "Nacetylglycine_imp", "sarcosine_imp", "dimethylglycine_imp", "betaine_imp") for (i in seq_along(met)) { my_formula <- paste0(met[i], "~egfr_v1_ckdepi+pc1+pc2+pc3+V1AGE01+GENDER") prep <- Scores(Z=metalofGT, formula = my_formula) save(prep, file = paste0("prep", i)) } ### Mark R.
