Hi, I have a small R question: how to print a single "\" character? I have the following results: > print("\") does not work > print("\\") [1] "\\" I need to make the following substitution as well, but it does not work either: > sub...

Hi, I am trying to use the Kuiper and Watson U^2 tests available in the CircStats or circular packages to test for uniformity on a circle. However, the implementation of these tests gives ranges of p-values that are...

Hi Thomas, thanks for the help, it does work. Regards, Firas. On Tue, 19 Apr 2005, Thomas Lumley wrote: > On Tue, 19 Apr 2005, Firas Swidan wrote: > > > Hi, > > I have a small R question: how to print a single "\" character...

Hi, I can not comprehend the linear fitting results of polynoms. For example, given the following data (representing y = x^2): > x <- 1:3 > y <- c(1, 4, 9) performing a linear fit > f <- lm(y ~ poly(x, 2)) gives...

Hi, I am experiencing a long delay when using dataframes inside loops and was wordering if this is a bug or not. Example code: > st <- rep(1,100000) > ed <- rep(2,100000) > for(i in 1:length(st)) st[i...

Hi, I am using the following command to print to a file (I omitted the file details): cat( paste( paste(orientation, start, end, names,"\n"), paste(start, end, "exon\n"), sep="")) where "orientation" and "names" are character vectors and "start...

Hi, I am having difficulties in finding ways to analyse scatter plots and quantitatively differentiate between them. Since this is best demonstrated by a figure, I have attached one with 4 subfigures (a)-(d). Qualitatively (and I hope you would...

How do I check that, and what quantification does it provide? Thanks, Firas. On Wed, 2008-07-23 at 21:20 +0530, Bogaso Cristofer wrote: > Have u checked skewness of data? > > -----Original Message----- > From: r-help-bounces at r-project...

Thanks for the clarifications. It seems the confusion resulted from making one assumption more than necessary regarding the behavior of poly(). Best wishes, Firas. On Fri, 2008-03-07 at 18:33 +1000, Bill.Venables at csiro.au wrote: > It...

Hi, thanks for the suggestions. However, for some reason the first one did not work. Trying cat( paste( paste(orientation, as.integer(start), as.integer(end), names,"\n"), paste(as.integer(start), as.integer(end),"exon\n"), sep="")) resulted in...
