One way to account for (or "control for") a covariate in a regression is to "take it out of the model" by regressing all other variables against that covariate and retaining only the residuals from those regressions. Is this the way to make the adjustment to the regression line intercept & slope? Or is there another way? The following plot printed, but I'm not sure if it is correct: plot8 <- ggplot(dataset, aes(x=predictor1 + predictor2, y=outcome1)) + However, I would like to create a similar scatterplot/regression line that corresponds to the following analysis: test8 <- lm(outcome1 ~ predictor1 + predictor2, data=dataset) Original analysis: test7 <- lm(outcome1 ~ predictor1, data=dataset)Ĭorresponding plot: plot7 <- ggplot(dataset, aes(x=predictor1, y=outcome1)) + So far, I have had no problem creating the scatterplot/regression line when there is only one predictor: (I understand that the data points don't change, just the intercept & slope of the regression line.) Default value is NULLĪ logical value.I am attempting to produce a scatterplot with a regression line whose intercept & slope are adjusted to account for another covariate in the model. Whether or not use value labels in case of labelled dataĪ character string of column name be included in tooltip. Whether or not use column label in case of labelled data Integer indicating the number of decimal places Maximum unique number of a numeric vector treated as a factor If true use geom_count instead of geom_point_interactiveĪn integer. Level of confidence interval to use (0.95 by default) Should the fit span the full range of the plot, or just the data "lm", "glm", "gam", "loess", "rlm"įormula to use in smoothing function, eg. display confidence interval around linear regression?
