Re: [R] ploting missing data
Try this:
library(zoo)
plot(na.approx(zoo(as.matrix(data[-1]), data[,1])), plot.type = "single")
See ?na.approx, ?plot.zoo, ?xyplot.zoo and vignette("zoo")

[R] ploting missing data
Hello, I have this kind of dataframe and have to plot it. data <- data.frame(sw= c(1,2,3,4,5,6,7,8,9,10,11,12,15), zehn = c(33.44,20.67,18.20,18.19,17.89,19.65,20.05,19.87,20.55,22.53,NA,NA,NA), zwanzig = c(61.42,NA,26.60,23.28,NA,24.90,24.47,24.53,26.41,28.26,NA,29.80,35.49), fuenfzig = c(162.51,66.08,49.55,43.40,NA,37.77,35.53,36.46,37.25,37.66,NA,42.29,47.80) ) The plot should have lines: lines(fuenfzig~sw, data=data) lines(zwanzig~sw, data=data) But now I have holes in my lines for the missing values (NA). How to plot the lines without the holes? The missing values should be interpolated or the left and right point directly connected. The function approx interpolates the whole dataset. Thats not my goal! Is there no plotting function to do this directly? Best Markus -- Dipl.-Tech. Math.
