[R] log of small values in R

Dear FriendsI am facing the problem of log values in R. The log(1-0.9) is giving -Inf while log(1e-18) gives finite answer. Any suggestion to deal with this problem? Thank you [[alternative HTML version deleted]] __

[R] How to get Mean Magnitude of Relative Error with caret library

Hi, I am using caret package and using nested resampling method (i.e. 5 fold for outer fold). I am getting the RMSE and MAE values, which are default to the caret library. My question is how can we implement the Mean Magnitude of Relative Error (MRE and MMRE) with caret. My code is the following:

Duncan, Great, many thanks, it works. Best, Le samedi 9 janvier 2021 à 21:13:30 UTC+1, Duncan Murdoch a écrit : Your x values aren't in increasing order.  When you plot lines(x, yfit), it joins the points in the order you give them, which jumps back and forth.  To fix, try o <-

Re: [R] How to avoid ggplot clipping the x axis [damn, replaces previous Email]

Hello, You are almost there. With scale_x_continuous use argument limits. ggplot(dat = tibDat, aes(x = x, y = y)) + geom_point() + scale_x_continuous(breaks = 1:6, labels = 1:6, limits = c(1, 6)) And with xlim it's not a vector c(1, 6), it's each element on

[R] How to avoid ggplot clipping the x axis [damn, replaces previous Email]

[I must try to remember that swapping between Rstudio and my Emailer is a recipe for hitting ctrl-enter and posting prematurely: sorry!] I am sure I am doing something stupid but I can't see what. I am plotting data and want the x axis labels to reflect the theoretical range of the x variable

[R] How to avoid ggplot clipping the x axis

I am sure I am doing something stupid but I can't see what. I am plotting data and want the x axis labels to reflect the theoretical range of the x variable which happens to be 1:6 but the observed values have range 2.6 to 5.9. I thought xlim(c(1,6)) should have got me that quite simply but it
