plotting log regression
Hello, How can you expect to see the fit line if you are ploting x and y values, not their logarithms? And your definitions of x and y are wrong, they should use c(). x <- c(1,2,3,4,5) y <- c(6,7,8,9,10) plot(log(x), log(y)) fit <- lm(log(y) ~ log(x)) # Same as glm abline(fit) Please read R-intro, in the doc folder of your installation of R. Hope this helps, Rui Barradas Em 14-12-2012 13:58, mrkooper escreveu:
I want to plot the regression line of a log regression into a plot with my normal, nonlog, data. for example x <- (1,2,3,4,5) y <- (6,7,8,9,10) plot (x,y) I tried a log-regression by a <- glm (log(y) ~ log(x)) and then i tried to insert the answer to my graph, where the standard values are shown: abline (a, col="red") unfortunately it does not work.... -- View this message in context: http://r.789695.n4.nabble.com/plotting-log-regression-tp4653087.html Sent from the R help mailing list archive at Nabble.com.
