Hi, I got problem in using title function to create a title for multiple plots presented together by par. As can be seen in the attached file, the title is displayed truncated and the subtitle doesn't get displayed. Here is the code: par(mfrow = c(1,2)) plot(c(1,2,3), c(9,8,7)) plot(c(1,2,3), c(9,8,7)) title(main = "Main title", sub ="Sub title",outer = TRUE,

Hello, I just have two questions I cannot figure out. 1) I would like to have a subtitle just below the main title on my graphs and I cannot figure out how to do this, is it possible? or is it only possible to have it at the bottom? 2) I need to run Conova post hoc test, do you know if it is coded in R? any package I would find this test in? Thank you very much for all the help Have a nice

Hi, We could use qqplot to see how two distributions are different from each other. To show better how they are different (departs from the straight line), how is it possible to plot the straight line that goes through them? I am looking for some thing like qqline for qqnorm. I thought of abline but how to determine the slope and intercept? Best wishes, Carol

Hi, What is the function for inverse normal transformation? Thanks, Carol [[alternative HTML version deleted]]

Hi, How to plot the same types of graphics on the same R graphic device? Suppose that we want to plot a vector y against x (using plot for instance). How is it possible to plot y against x for different values of these two vectors on the same device so that the plots could be compared? Cheers, Carol [[alternative HTML version deleted]]

Hello, It might be an easy question but if you have many variables to fit in the lm function, how do you take all without specifying var1+var2+...+var2100 in the terms parameter in response ~ terms? Cheers, Carol

R 2.4.0 for Windows The following plot appears as a squared window (as all r-plots) Not all subtitles are visible, but all subtitle will appear, when changing the aspect ratio of the plot window with the mouse to a wide format. But does not work when using the save as postscript menu item from the plot window. is there any solution for that? opar <- par(mfrow = c(2,2), oma = c(0, 0, 1.1,

Hello, How is it possible to sort dates in R? Cheers, Carol

Dear All, I tried to invoke plot for a matrix of?196475 x2 dimension. I loaded the data with read.table. On one dimension, there are strings (names) and on the other dimension, the floats between 0 and 1. When I invoked plot by setting x to names and y to floats and ylim = c(0,1), I got the following error message: Error in rep.int(boxwex, n) : negative length vectors are not allowed Does it

I want to add an outer subtitle to my 2x3-plot, but it's distance to the lowest plots is very high: 6 lines or more?! If I choose oma=c(5,0,2,0), it lies out of the plotting region and disapprears. Obviously I make something wrong here. Help appreciated, Thomas x=seq(from=1, to=3.5, length=100) par(mfrow = c(2, 3), oma=c(6,0,2,0)) ## oma=c(5,0,2,0) will not work?! plot(x,x^2) plot(x,sin(x))

Hi, Is it normal to get intercept in the list of covariates in the output of survreg function with standard error, z, p.value etc? Does it mean that intercept was fitted with the covariates? Does Value column represent coefficients or some thing else? Regards, ------------------------------------------------- tmp = survreg(Surv(futime, fustat) ~ ecog.ps + rx, ovarian,

Hi, Having a set of values (non-time series data), what are the approximation functions that could determine the trend of the values? Cheers, Carol [[alternative HTML version deleted]]

Hi, It might be a primitive question but how it is possible to determine if a variable is initialized in an environment? Suppose that we start a R session and wants to run a script which use the variable i. Which function could evaluate if i is already initialized or not and if not, then ask interactively the user to set it? This is to avoid the error message: object i is not found. Regards,

Have UI that simplifies running code from another (internal) package, allowing user to set values on fields I basically grabbed from results of calls to formals() for various functions. That works fine for the most part. But it was requested to investigate some type of popup help or something for each field. Since I already wrote the information in the dot-Rd files for what should be displayed,

Hi, How is it possible to extract athe elements of a list of vectors in a fixed position? suppose that I have a list of 2-element vectors, how can I extract the 2nd element of all vectors in the list? Can it be done with indexing and not by element name? Thanks carol So in this example, I want to extract 2 and 4 v = list (c(1,2), c(3, 4)) > v [[1]] [1] 1 2 [[2]] [1] 3 4

Hello, I want to create a figure that consists of a collection of 16 graphs on 4 rows. I am using nf <- layout(matrix(seq(1,16), 4,4, byrow=TRUE), respect=TRUE) boxplot(... to create the layout of my 16 graphs. It works really well. However, I'd like to add sub-titles that would apply to each row of 4 graphs. More specifically, I'd like to have something like: subtitle 1

Hi, I wanted to plot the histogram of a vector and then, plot the density function of subsets of the vector on the histogram. So I use truehist in MASS package and lines(density) as follows: length(b) = 1000 truehist(b) lines(density(b[1:100])) however the density plot of the first 100 points exceeds the max of y axis (see attached). how is it possible to make a graphics so that the density plot

Hi, Although I set check.names to FALSE in read.table, the duplicate names get modified. What should be done in this case? the text file to be read by read.table AM2      AM2     AM2     FAL 2               3             4         5 1               -1           -3        -2 t = read.table ("my_file", check.names = FALSE, header = T) > t AM2      AM2.1     AM2.2     FAL

Hi, It might be a trivial question but how do you store matrices of different dimensions read from a file or in a loop together? The best solution might be a list but I don't store the first matrix  correctly:  m = rbind(c(1,2),c(3,4),c(5,6)) t=rbind(c(1,2),c(5,6))  l = list(m) > l = list(l,t)    #I assumed that at the begining I don't have m and t at the same time to do list(m,t),

Hi, Is there any equivalent for ifelse (except if (cond) expr1 else expr2) which takes an atomic element as argument but returns vector since ifelse returns an object of the same length as its argument? x = c(1,2,3) y = c(4,5,6,7) z = 3 ifelse(z <= 3,x,y) would return x and not 1 thanks
