Hi Olga, not directly related to your question. We have also a server installation and subsequently our IT department determines which version and packages I can use on R. A few days ago I have switched to R-portable. Works without any problems from my USB stick on any locked-for-installation

[R] Plotting one dot in a graph

I'd like to plot a point at the intersection of these two curves. Thanks x - seq(.2, .3, by = .01) f - function(x){ x*cos(x)-2*x**2+3*x-1 } plot(x,f(x), type = l) abline(h = 0) __ R-help@r-project.org mailing list

I searched with print x-axis label in 45 degree which didn't return useful links. Apparently I used poor search keywords. - Original Message From: David Winsemius dwinsem...@comcast.net To: Marc Schwartz marc_schwa...@me.com Cc: array chip arrayprof...@yahoo.com;

Yes, I'm playing around with other things but the points() function is what I was looking for. Thanks On Aug 12, 2010, at 12:47 PM, David Winsemius wrote: On Aug 12, 2010, at 3:43 PM, TGS wrote: I'd like to plot a point at the intersection of these two curves. Thanks x - seq(.2, .3, by =

Re: [R] Plotting one dot in a graph

Actually I spoke too soon David. I'm looking for a function that will either tell me which point is the intersection so that I'd be able to plot a point there. Or, if I have to solve for the roots in the ways which were demonstrated yesterday, then would I be able to specify what the

Re: [R] help usin scan on large matrix (caveats to what has been discussed before)

I did. Did not work. Did you try your code? The matrix did not result into integer numbers as expected. MY approach resulted in a correct scan result, at least. M. Martin Tomko wrote: Hi Peter, apologies, too fast copying and pasting. So, here is the explanation: f-C:/test/mytab.txt;

Re: [R] reading fixed width format data with 2 types of lines

I don't know if it's elegant enough for you, but you could split the file into two files with 'grep ^3 file file_3' and 'grep ^4 file file_4' and then read them in separately. Tim On Thu, Aug 12, 2010 at 01:57:19PM -0400, Denis Chabot wrote: Hi, I know how to read fixed width format data

Re: [R] Plotting one dot in a graph

I was meaning something like the following: x - seq(.2, .3, by = .01) f - function(x){ x*cos(x)-2*x**2+3*x-1 } plot(x,f(x), type = l) abline(h = -.1) But I'm guessing uniroot will do this?---I haven't looked far into the uniroot function to see if it will solve this. On Aug 12, 2010,

Thank you all for the quick responses. So far as I've checked, Marc's solution works perfectly and is quite speedy. I'm still trying to figure out what it is doing. :) Henrique's solution seems to need some columns somewhere. David's solution does not find all the other measurements,

[R] Scatterplot - Overlap Frequency

Hi listers... I am working o a scatterplot where I would like to plot the variables according with another frequency variable. Another friend here proposed this code... x - rnorm(10) y - rnorm(10) ind - c(1,0,1,0,1,0,1,1,0,0) plot(x, y, col = ind + 1, pch = 16) # 1 is black, 2 is red But in my

Re: [R] Plotting one dot in a graph

# just to clean it up for my own understanding, the difference approach as you had suggested would be x - seq(.2, .3, by = .1) f1 - function(x){ x*cos(x)-2*x**2+3*x-1 } plot(x,f1(x), type = l) abline(h = -.1) abline(v = x[which.min(abs(diff((f1(x) - (-.1))**2)))], lty = 'dotted')
