It seems that there is a problem in displaying subtitle in general, independently from multi-plot display. when I do plot (c(1,2,3), c(9,8,7), type = "l") title(main = "Main title", sub ="Sub title",cex.main=2, cex.sub = 2) subtitle doesn't get displayed > --- On Sat, 11/21/09, David Winsemius <dwinsemius at comcast.net> > wrote: >

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

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

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,

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

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

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, 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, 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, Having a vector x of float type without any assumption of its distribution (mean, variance etc), how to generate another vector that is correlated with x? Extensibility: how to simulate more than two correlated vectors (again float type and no preference for their distribution and without having vector x)? Cheers, Carol

Hi, How to turn a character string into an unevaluated R object? I want to load some files in a directory into data matrix R objects. I could do this with read.table and assign (see below). Then, I want to turn the character string representing a file name (the evaluated expression of i) into an unevaluated R object. Basically, I want to create matrices whose names are the same as the related file

Hi, 1- How is it possible to use the name of a generic function as the name of a function which is not related to the generic function? For example, if I define predict.my.function, R will relate it to predict function and I'll get the following warning when I run R CMD check * checking S3 generic/method consistency ... WARNING predict: ? function(object, ...) predict.my.function

Hi, Is the following command used to increase the memory or any other command when a background R job is run? R --min-vsize=vl --max-vsize=vu --min-nsize=nl --max-nsize=nu --max-ppsize=N source: http://stat.ethz.ch/R-manual/R-patched/library/base/html/Memory.html Thx Carol [[alternative HTML version deleted]]

Hello, It might be a trivial question but I just wanted to find out the relationship between sdev and proportion of variance generated by prcomp. I got the following result from my data set ???????????????????????????? PC1????? PC2????? PC3 Standard deviation???? 104.89454 15.40910 9.012047 Proportion of Variance?? 0.52344? 0.01130 0.003860 Cumulative Proportion??? 0.52344? 0.53474 0.538600
