@guhjy I can't reproduce the error. I just re-installed FRB and ran the above without problems (output below). Did "install_github" build the package properly when your last ran it?

library(devtools)
install_github("msalibian/FRB")
library(FRB)
library(robustbase)
data(NOxEmissions)
a <- lmrob(LNOx ~ LNOxEm + sqrtWS, data=NOxEmissions)
set.seed(123)
( tmp <- frb(lmrob.object=a, nboot=1000, return.coef=FALSE) )

@msalibian: The problem has been solved. Thank you! However, this installation erases the CRAN FRB package ( https://cran.r-project.org/web/packages/FRB/index.html), which has the same name as your package. 1. What to do if two packages have the same name? 2. What are the differences between your package and the CRAN "FRB" package? 3. How to compare the coefficients between 2 lmrob models? e.g.

((a <- lmrob(mpg ~ disp + hp + wt, data=mtcars)))

Call: lmrob(formula = mpg ~ disp + hp + wt, data = mtcars) \--> method = "MM" Coefficients: (Intercept) disp hp wt 36.6321312 0.0009983 -0.0303098 -3.9208073

((b <- lmrob(mpg ~ disp + hp + qsec, data=mtcars)))

Call: lmrob(formula = mpg ~ disp + hp + qsec, data = mtcars) \--> method = "MM" Coefficients: (Intercept) disp hp qsec 38.02182 -0.02632 -0.03292 -0.41532

1. What to do if two packages have the same name?
   Thanks for pointing this out. I think I will need to rename my package. Maybe to FRB.reg, or something that reflects the fact that my package only deals with linear regression models.

2. What are the differences between your package and the CRAN "FRB" package?
   The methodology is the same. My package deals with (scalar-response) linear regression models, the other one deals with multivariate models.
