Hi, I’m trying to get smooth curves connecting points in a plot using "spline" but I don’t get what I whant.
Eg.: x<-1:5 y <- c(0.31, 0.45, 0.84, 0.43, 0.25) plot(x,y) lines(spline(x,y)) Creates a valley between the first and second points, then peaks at 3rd, and another valley between 4th and 5th. I’m trying to get a consistently growing curve up to the 3rth point and then a decrease like with SigmaPlot spline curves or with Excel. I tried with different spline arguments and also lowess and loess, with no success. Any ideas? Thanks. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
