[R] Accessing individual variables from summary of lm
I am trying to access the R2, intercept, and slope out of the summary from an lm so that I can insert it into a database using RODBC. How can I access these individually? thanks in advance, Ben. -- View this message in context: http://www.nabble.com/Accessing-individual-variables-from-summary-of-lm-tp18582274p18582274.html Sent from the R help mailing list archive at Nabble.com. __ 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.
Re: [R] Accessing individual variables from summary of lm
Thanks for your help! If you wouldn't mind, how do I access the individual components inside coefficients matrix? thanks, Ben.

[R] Add a Vector to a Matrix
I know there is a very simple answer to this question, but it eludes me. I need to insert a vector into a matrix. So if I have a 2 column matrix with 5 rows, I need to insert in an additional vector so there is now 6 rows without overwriting any of the data in the matrix already. thanks, Ben. -- View this message in context: http://www.nabble.com/Add-a-Vector-to-a-Matrix-tp18667839p18667839.html Sent from the R help mailing list archive at Nabble.com. __ 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.
[R] Polynomial regression help
I have a simple X, Y data frame that I am trying to run regression analysis on. The linear regression looks great, but when I use lm(formula = y ~ poly(x, degree = 5)) I get the same coeffecients. So for example if I use degree =3 my formula would look like y = 4.2 x^3 + 3.2x^2 + 2.1x + 1.0 and my degree 5 would look like y = 6.5x^5+ 5.4x^4 + 4.2 x^3 + 3.2x^2 + 2.1x + 1.0, which doesn't make sense to me. I was wondering if someone knew what I was doing wrong or if this is correct? thanks, Ben. -- View this message in context: http://www.nabble.com/Polynomial-regression-help-tp19042447p19042447.html Sent from the R help mailing list archive at Nabble.com. __ 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.
[R] Plotting multiple curves on a plot
Greetings! I was wondering how to plot multiple equation on the same plot with the data? So if I have three equations: 1.y= 2.31X + -2.2 2.y= 2.27X^2 + 5.63X + 0.52 3.y= -1.53X^3 + 1.92X^2 + -4.72X + 4.57 and a datafram or a 2D matrix. I would also like the equations in different colors, but that is extra! thanks in advance, Ben. -- View this message in context: http://www.nabble.com/Plotting-multiple-curves-on-a-plot-tp19132217p19132217.html Sent from the R help mailing list archive at Nabble.com. __ 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.
