Dear all, I have recently installed R on a Red Hat Enterprise Linux (RHEL5) system. But I am unable to load R and it is giving the following error : */usr/local/lib/R/bin/exec/R: error while loading shared libraries: libreadline.so.5: cannot open shared object file: No such file or directory* I have checked for the presence of the above mention library and found that the library

How to add trendline (i.e. straight line passing through maximum points) in graph. I have worked on the data given below. Please tell me how to add trendline in the graph. The script is as follows =================================== start ==================================================== # The data is as follows data <- c( 0.01, 0.02, 0.04, 0.13, 0.17 , 0.19 , 0.21 , 0.27 , 0.27 ,

Hi I would like to display the trendline and the R-square value in a xy scatter in R. For example if I want to plot f vs g I add the trendline using the commands below >library(quantreg) >plot(f,g) >abline(rq(g~f)) however I don't know how to display the R2 in the graph. Thank you in advance. Kind regards Maria [[alternative HTML version deleted]]

Dear all, I am using abline(lm ...) to insert a linear trendline through a portion of my data (e.g. dataset[,36:45]). However, I am finding that whilst the trendline is correctly displayed and representative of the data portion I've chosen, the line continues to run beyond this data segment and continues until it intersects the vertical axes at each side of the plot. How do I display the

Hi all, I have a dataset which consists of 2 columns. I'd like to plot them on a x-y scatter plot and fit an exponential trendline. I'd like R to determine the equation for the trendline and display it on the graph. Since I am new to R (and statistics), any advice on how to achieve this will be greatly appreciated. Many thanks, Chris -- View this message in context:

Hi, I am trying to fit a logarithmic trendline to a scatterplot of a species accumulation curve. I've tried abline, lines, curve and scatter.smooth but none of these work. Can anyone help please, Kyran

Hi all , I am facing some problems with 'ls' command. Whenever I use it I get the following error : ls("KEGG.db") Error in as.environment(pos) : no item called "KEGG.db" on the search list ls("pkgname") Error in as.environment(pos) : no item called "KEGG.db" on the search list and this is true for any package. Can anything be done

Hi everyone, I'm trying to determine the significance of a trendline. From my internet search months ago, I came across the following post. I modified tim and dat for simiplicity. tim <- 1:10 dat <- c(0.17, 1.09 ,0.11, 0.82, 0.23, 0.38 ,2.47 ,0.41 ,0.75, 1.44) fstat <- summary(lm(dat~tim))$fstatistic p.val <-

I just set up Ubuntu Hardy Heron on my Compaq Presario C712nr laptop, and I was hoping that someone could help me to set up Steam so that it will fully function. I have previously tried this, yet was unable to get the Steam Community working properly with its chat functions and such. This was a real dealbreaker for me, as Steam Community is my primary social networking service. If anyone could

Here is another implementation of Markdown, this time in c++ using the Boost Spirit library. Spirit Markdown is written in (hopefully!) idiomatic modern c++ and a full suite of unit tests are provided. It is licensed under the Boost Software License (OSI compliant). The purpose of writing this is: * for me to gain expertise in the use of Spirit, both through direct experience and public review,

I am trying to set up a function which processes my data according to the following rules: 1. if (x[i]==0) NA 2. if (x[i]>0) log(x[i]/(number of consecutive zeros immediately preceding it +1)) The data this will apply to include a variety of whole numbers not limited to 1 & 0, a number of which may appear consecutively and not separated by zeros. Below is an example with a detailed

I am indebted to Deepayan Sarkar for lattice graphics, Fritz Leisch for Sweave and the authors of the beamer package for LaTeX. For me these are a "killer app" combination. I wouldn't want to go back to creating presentations in any other way. When I create a presentation I use a Makefile that allows me to the presentation version of the slides, a 4-up version for printing on

Good morning once more. My problem of yesterday has been addressed. Having learned a few tricks from that, I wish to ask another question in connection with that. My data is a cosmic ray data consisting of dates and counts. When I plot a graph of counts versus dates, the resultant signal shows a number of maximum and minimum points. These minimum points (turning points) are of interest to me.

OK this is bound to be something silly as I'm completely new to R - having started using it yesterday. However I am already warming to its lack of 'proper' GUI... I like being able to rerun a command by editing one parameter easily... try and do that in a Excel Chart Wizzard! I eventually want to use it to analyse some chemotherapy response / survival data. That data will not be

There are a couple of points to keep in mind when doing a log-transform of an exponential model, such as -- y = a*exp(b*x) 1. The implicit statistical model is multiplicative in the error. The implied statistical model of the log transform is -- log(y) = log(a) + b*x + u which implies -- y = a*exp(b*x)*exp(u) A linear regression in the log

Hi, Is there a way to plot trendline with quantmod package? There is addLines function in the package but I can't seem to figure out how to use it (not well documented): > args(addLines) function (x, h, v, on = 1, overlay = TRUE, col = "blue") NULL so arguments "h" and "v" add horizontal and vertical lines. How does argument "x" work? I would like

Hi all, [this is a bit hard to describe, so if my initial description is confusing, please try running my code below] #WHAT I'M TRYING TO DO I'd appreciate any help in trying to speed up some code. I've written a script that converts a matrix of integers (usually between 1-10,000 - these represent allele names) into two new matrices of normally distributed values (representing

Some new stuff in the directories horn and strings. I am indebted to Nathan Sharfi for totally reorganizing the web page of pan.zipcon. It was a heroic effort, as there was considerable mess. Included were important help for Windows and Mac users, -- how to get free music players and how to use wget for download. This contribution is a milestone in the popularization of ogg-vorbis. See
