Hi there, I'm trying to make a scatterplot of removed versus duration for each type of bee. No matter what I try, I can't seem to get my code to work. Any help would be appreciated. Thanks! My r-code: dat$BEE <- with(dat, factor(BEE, c(1,2))) plot(REMOVED~DURATION,pch=BEE, col=BEE) REMOVED DURATION BEE 1 0.07 2 QUEEN 2 0.10 5 QUEEN 3 0.11 7 QUEEN 4 0.12 11 QUEEN 5 0.15 12 QUEEN 6 0.19

Hello, I am trying to write a code to estimate the  residual standard error and create a confidence interval using bootstrap, since it does not follow a normal distribution. So far I have found a linear model for the data (m1<-lm(y~x+I(x^2))), but I am not sure how to create the bootstrap code to estimate its residuals. Thank you for any input, Kelsey [[alternative HTML version deleted]]
