I am very new to R studio, may be this is a very basic question but I am really not understanding what's going on. Can someone please explain. Thanks in advance.
So, I am trying to fit a model and then use anova type 2. But while doing this, I am getting an error: Error: $ operator is invalid for atomic vectors
My code is:
data <- read.table("breadwrapper.txt",header=TRUE)
y <- data$Y
x1 <- data$X1
x2 <- data$X2
x3 <- data$X3
ModelA <- lm(y ~ x1+x2+x3, data = data)
I am using a local data file. What should I do further?
