[R] add lowess predicted line to scatter plot

Hi, I have a scatter plot of the variables GNI and Lifeexp (Gross National Income and Life Expectancy, both metric). So I plotted them and I want to add a regression line and a lowess line. I use lowess and not loess because I have missing values. My code: plot(GNI,Lifeexp) abline(lm(Lifeexp~GNI),

Re: [R] correlating matrices

Hi before you can use predict you need to do lm(whatever.). If you used lm(whatever., na.action=na.exclude) predict will give you results with correctly placed NA values. Regards Petr > -Original Message- > From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- > project

[R] eval and tcltk : target of assignment expands to non-language object

Hi everyone, I have a problem to assign a value with tcl/tk ths is the code ( it should be simple to understand) : library(tcltk) valA<-tclVar("0") valB<-tclVar("0") valC<-tclVar("0") id<-"A" out<-"1" out2<-"2" print(paste("tclvalue(val",id,")",sep="")) # ok print(as.name(paste("tclvalue(val",

Re: [R] Confused by code?

Hello, It is pretty basic, and it is deceptively simple. The worst of all :) When you index a matrix 'x' by another matrix 'z' the index can be a logical matrix of the same dimensions or recyclable to the dims of 'x', it can be a matrix with only two columns, a row numbers column and a column

Re: [R] Regression Problem

What is it you think as.numeric accomplishes for you? A reproducible example as requested in the posting guide might clarify. Making factors and leaving them that way seems more productive. --- Jeff Newmiller

Re: [R] Background color in a grid plot seems to interfere with plot()

Same reason. grid() is part of base graphics, which are incompatible with grid graphics. Perhaps you want grid.grill(), which you could find out about in the grid graphics vignette mentioned earlier. --- Jeff Newmiller

[R] POSIXct coerced into numeric when filling a data frame

Hello I have a list of POSIXct objects, from which I want to extract those values that match a specific date, keeping them in POSIXct format. For a specific date there is 0-2 matching values. As an example (the actual list and objects are much longer): x<-list() x[["first"]]<-as.POSIXct(c("2011
