Aligning Data frame with missing values

Question

I\'m using a data frame with many NA values. While I\'m able to create a linear model, I am subsequently unable to line the fitted values of the model up with

Answer 1

I use a simple for loop. The fitted values have an attribute (name) of the original row they belonged to. Therefore:

for(i in 1:nrow(data)){
  data$fitted.values[i]<-
    fit$fitted.values[paste(i)]
}

"data" is your original data frame. Fit is the object from the model (i.e. fit <- lm(y~x, data = data))
