Hi
I am working with attached dataset for linear regression problem and have performed the below steps :

dataset<- read.csv("LinearRegressionCase.csv")
View(dataset)
summary(dataset)

Function to replace #NULL with NA

nullrep<-function(x){
ifelse(x=="#NULL!",NA,x)

}

df<- as.data.frame(apply(dataset,2,nullrep))
summary(df)

Now I need to replace NA with mean or 0 value but for me it is throwing error saying that it needs to be converted to numeric...

Please help me out in removing the NAs (using function) and converting the variables to numeric.
