How to Loop/Repeat a Linear Regression in R

Question

I have figured out how to make a table in R with 4 variables, which I am using for multiple linear regressions. The dependent variable (Lung) for each regression is taken f

Answer 1

The question seems to be about how to call regression functions with formulas which are modified inside a loop.

Here is how you can do it in (using diamonds dataset):

attach(ggplot2::diamonds)
strCols = names(ggplot2::diamonds)

formula <- list(); model <- list()
for (i in 1:1) {
  formula[[i]] = paste0(strCols[7], " ~ ", strCols[7+i])
  model[[i]] = glm(formula[[i]]) 

  #then you can plot or do anything else with the result ...
  png(filename = sprintf("diamonds_price=glm(%s).png", strCols[7+i]))
  par(mfrow = c(2, 2))      
  plot(model[[i]])
  dev.off()
  }
