Re: [R] Q - scatterplot, plot function & trellis linear regressions???

HI R-listers, Thanks for the replies I am convinced of Q 1 and 2. Q 3 - I am still unsuccessful. Aeventexhumed has three events A, B and C. I am unable to make 3 windows of scatterplot graphs side by side showing the difference in regression of each event. With and without lattice I have trie

Re: [R] Q - scatterplot, plot function & trellis linear regressions???

Thank you Simon, Yes this was in the library(car). There were no negative values in the scatterplot graph or negative limits displayed. Q-2 Are you sure the lines from the scatterplot are not this?: solid green line: linear regression solid red line: non-linear regression upper dashed red line: u

Re: [R] Q - scatterplot, plot function & trellis linear regressions???

I presume you mean car::scatterplot A1) plot is a generic function for plotting 'things' and scatterplot is a specific tool provided by that library A2) from the documentation one infers that 1) the straight line is a regression line 2) the other lines are produced using loess

[R] Q - scatterplot, plot function & trellis linear regressions???

Hi R-listers, Q1) What is the difference between the scatterplot and plot function? Q2) I am able to make a graph with the scatterplot function: scatterplot(DevelopIndex ~ Veg, + data = Turtle, + xlab = "Vegetation border (m)", + ylab = "Embryonic developme
