Subset of predictors using coefplot()
问题 I'd like to do a plot of coefficients using coefplot() that only takes into account a subset of the predictors that I'm using. For example, if you have the code y1 <- rnorm(1000,50,23) x1 <- rnorm(1000,50,2) x2 <- rbinom(1000,1,prob=0.63) x3 <- rpois(1000, 2) fit1 <- lm(y1 ~ x1 + x2 + x3) and then ran coefplot(fit1) it would give you a plot displaying the coefficients of the intercept, x1, x2 and x3. How can I modify this so I only get the coefficients for say, x1 and x2? 回答1: You can use the
