similar to: Plot using colors

Hello Everybody, I'm trying to plot(x,y) using different colors. I have to cut (x,y) into sub intervals. And I want to plot this sub intervals using colors. But infortunally I don't know how to do this with R. Can any body help me please? My code is looking like : x<-c(tvar[1:t0],tvar[t0:(ts)],tvar[ts:n]) F<-c(var[1:t0],var[t0:(ts)],var[ts:n]) plot(x,F,xlab="Zeit

Dear R user, I have written a function which returns max,min and variation of a power (see below) Power is a given matrix(1,n) I call the function >Variation<-VAR(p,(n-deltat)) Now the problem is when I want plot(Results[1],Results[2]). Not possible! I become the following error (in english it means: Error in as.double.default(x) :Object cannot be transformed in double) >

Dear R users, Is it possible to add comments in a plot window?

Dear R users, I want to read a file like following : if it is a table then z <- read.table(pathname, dec=".", header=TRUE) else if it's not a table (image,doc,...) then send an error or something like that acually I have a read.table in the beginnig of my R code, and if my data is not a table I become in my R console : fail in scan. So the question is how to check the nature of

Dear list I would like to be able to group terms in a formula using a function that I will call tvar(), eg. the formula Y ~ 1 + tvar(x:A) + tvar(z) + u + tvar(B) + tvar(poly(v,3)) where x,u and v are numeric and A and B are factors - binary, say. As output, I want the model.matrix as if tvar had not been there at all. In addition, I would like to have information on the grouping, as a vector

Hallo Tk experts, the Tcl/Tk package allows to define very nice widgets for starting R functions, for printing results and for interactive parameter input. tkdensity.R and tkttest.R demonstrate this and both demos explain how some of the tk functions can be used. For constructing new widgets I would like to see further examples showing Tcl/Tk package in action. Therefore my question: Is there a

Hi, Windows 7 64-bit clients have a very high latency (constantly rising) using of tinc. 32-bit clients are working with normal speed. Does anyone have a solution for this problem? Viele Gr??e Dirk Krause

Hi Paul, Sounds like you have your answer, but for fun I thought I'd try solving your problem using only a regular expression query and base R. I believe this works: > txt <- "Patient had stage IV breast cancer. Nothing matches this sentence. Metastatic and breast match this sentence. French bike champion takes stage IV victory in Tour de France." > pattern <-

Hello All, I need some help figuring out how to extract combinations of target words/terms from cancer patient text medical records. I've provided some sample data and code below to illustrate what I'm trying to do. At the moment, I'm trying to extract sentences that contain the word "breast" plus either "metastatic" or "stage IV". It's been some

Dear helpers, In an attempt to use a loop to generate graphs in a for loop in run into a problem. The plan is to fill each page with eight graphs (mfrow = c(4,2)) in to two columns. Only the buttom graphs ( meaning every fourth graph) have tick labels on the x axis to preserve space. I used an if .... Else statement to achieve that. The problem is that the first eight graphs are skipped

Hi Bert, Thanks for your reply. It appears that I didn't replace the variable name "sampletxt" with the argument "x" in my function. I've corrected that and now my code seems to be working fine.

Hi, sorry if this is explained somewhere but I didn't find anything. How can I use "Anova" from the car package to test a modell without between subject's factors? Suppose I have the following data mat.1 mat.2 mat.3 di ex 1 85 85 88 1 1 2 90 92 93 1 1 3 97 97 94 1 1 4 80 82 83 1 1 5 91 92 91 1 1 6 83 83

Hi Robert, Thank you for your reply. An attempt to solve this via a regular expression query is particularly helpful. Unfortunately, I don't have much time to play around with this just now. Ultimately though, I think I would like to implement a solution something along the lines of what you have done. I have a book on regular expressions that I am now starting to read. In the meantime, the

Have you looked at the CRAN Natural Language Processing Task View? If not, why not? If so, why were the resources described there inadequate?

Dear R-Experts, I have the following command lines: windows() plot(0:60, 0:0.896, type="n", xlab="Zeit [min]", ylab="Absorptionsmessung bei 600nm",main="Zellwandstabilit?t" ) dev.off() Can anyone say me why the plot command does not work and how the correct one should look like? Important is: x-axis goes from 0 to 60 and the y-axis from 0 to 0.896!

Hi R users, I have collected data which I plot(x,y).The problem it has oscillations. Now i'm trying to "make better" this curve with a smooth line starting let's say @x=300 s. And then collect my new datas. But I don't know how doing this. Perhaps a linear regression ?? See .jpeg foto. Thanks for any help it will be given.

Hello R users, Is it possible after making a plot(x,y) to change axis scale? For example : I have a range of 0 to 3000 in my y-axis and I want to make a zoom between 2000 and 3000.

I'm trying to do realize the following: I have 4 condtions. If all conditions are satisfied I will paste("PASS") If any of these is not satisfied I will paste("FAIL"). But I have to paste the corresponding failure. ifelse is a good solution but for a 2 conditions. Maybe switch or something like this. Does anyone have an idea how to do? Thanks in advance.
