How to solve the variable length differ error

First post here. I am trying to create a linear regression with R by regressing each variable in the dataset with INFLATION.

for(i in 1:4) {             
  predictors_i <- colnames(data.all.inflation)[i+1]   
  summary(lm(predictors_i ~ data.all.inflation$INFLATION))
}

After running the code, the following error message appears:

Error in model.frame.default(formula = predictors_i ~ data.all.inflation$INFLATION, : variable lengths differ (found for 'data.all.inflation$INFLATION')

Please let me know if there are any more details that you want/need.Thanks!
