Hi, I've been trying to set the directory for choose.files as follows: [R2.9.0 running on XP] setwd("C:/Documents and Settings/2/Data") getwd() infile2 = choose.files(filters = Filters[c("txt","All"),], caption = "Choose ECD datafile") #<...do a bunch of stuff...> It appears the working directory isn't updated until after choose.files()

write.table with large data frames takes quite a long time > system.time({ + write.table(df, '/tmp/dftest.txt', row.names=FALSE) + }, gcFirst=TRUE) user system elapsed 97.302 1.532 98.837 A reason is because dimnames is always called, causing 'anonymous' row names to be created as character vectors. Avoiding this in src/library/utils, along the lines of Index:

Another question, Is anybody using the Tellabs 2572 EC with a PRI. When we moved from our analog lines to a PRI, I thought it would be simple stuff moving the EC to the PRI. Changed signaling, made sure that channel 24 wasn't being ECd and everything came up. But, I was getting complaints of random echo on the PRI. Local echo. Also, we weren?t able to do any kind of modem dial-outs (Adit

Hi, all ecdf function (Empirical Cumulative Distribution Function) in "stats" package counts from smaller values to larger values. However, I want to draw it by counting from larger value to smaller values and I couldn't find options for this purpose. How can I draw ecdf or ecdf like graph by counting from larger values to smaller values. Thank you in advance. Hyunchul Kim

I'm trying to implement a connection between two processes using a simple socket mechanism. The messages are rather long object stored as JSON. R is crashing with a segmentation fault when I try to read my test message (which is 5305 bytes long). I first send the length in bytes and then I send the actual message. Here is my R code: library(jsonlite) library(futile.logger)

Dear R developer, I am not quite sure, if I should post my concern as a wish to r-bugs at r-project.org. Thus, as recommended, I first send an email to you. My request is the following: I would appreciate, if it was possible to obtain a plot of a 'stepfun' with a strict interpretation of xlim. What I mean: sf <- stepfun(1:4, 1:5) plot(sf, xlim=c(0,10)) does not bound the function to

i've noticed a strange problem when plotting a stepfun. according to the documentation, the xlim parameter should bound the range of the function being plotted, and is returned as the extreme two values (i.e. first and last) in the vector t from the plot.stepfun call. instead, it plots beyond the desired range (although the limits are preserved for the viewing space). to reproduce: foo

Hello list:) I have lots of values which I would like to get a histogram outline out of. An example of what I am talking about: testdata = runif(100) bbb = seq(0,1, by = 0.01) hist(testdata, breaks = bbb) I would like to get the outline of the resulting histogram. Now, I think that I can do this using the stepfun function. However, I am uncertain of how to get to the data the stepfun function

Thanks for the link.? Somehow the information about how to join the bugzilla site was not available at bugzilla and buried in the CRAN web site instructions on reporting bugs (which pointed me at Bugzilla and not the page you showed me). The example is pretty minimal.? I left the tracing statements (flog.trace()) and the toJSON, fromJSON in as I thought they might provide some context for

hi y'all, I am wondering if there is any special command, function, package, etc to help me doing a cumulative distribution function, with y-scale - probability scale. I tried the help in R and i got the following answers: cumsum(base) Cumulative Sums, Products, and Extremes ecdf(stepfun) Empirical Cumulative Distribution Function cpgram(ts) Plot

Hi. I have the following two ecdf plots in one graph: plot( ecdf(....), do.points=FALSE, verticals=TRUE, main=paste("Ecdf of distances ",DIM,sep=""), col="red" ); lines( ecdf(....), do.points=FALSE, verticals=TRUE ); How do I change the color of the resulting graph? Adding col="red" to either plot or lines results in an error

Hi r-users,   I would like to compare the cdf between historical and predicted. My x.obs and x.pre are the frequency data in classes of 0-300. I tried: plot(ecdf(x.obs),ecdf(x.pre),type="l",col="red")   and it gives me: Error in plot.stepfun(x, ..., ylab = ylab, verticals = verticals, pch = pch) :   argument 4 matches multiple formal arguments   Thank you so much for any

Hi all R users I would like to know how acess the coordinates of the ECDF object. I look for the example, in this part: ###################### print(ls.Fn12 <- ls(env= environment(Fn12))) ###################### but I do not know to extract the Y coordinate and put it in other variable. My objective is to make a plot and identify the points with labels. ############# Example by

Hi! I've noticed the ecdf() R code (R ver. 2.5.0) contains two call to sort: --- [R-code] --- ecdf <- function(x) x <- sort(x) n <- length(x) if (n < 1) stop("'x' must have 1 or more non-missing values") vals <- sort(unique(x)) rval <- approxfun(vals, cumsum(tabulate(match(x, vals)))/n, method

Hi. I'm trying to plot two ecdf's on the same graph using two different colors. I can plot using the same color, but it doesn't work when I change colors? Any suggestions? Thanks in advance for your help. x <- c(0.80, 0.83, 1.89, 1.04, 1.45, 1.38, 1.91, 1.64, 0.73, 1.46) y <- c(1.15, 0.88, 0.90, 0.74, 1.21) plot(ecdf(x)) # it works without col='blue', but doesn't

I’m using the edcf function to look at a number of empirical distributions graphically for run-time analyses of stochastic optimization algorithms. When dealing with problems where the optimal solution for these problems is always found everything is fine and the graphs are very useful for comparative observations. These distributions have a vertical axis height of one i.e. a probability of one.

Hello, is ot possible to draw two ecdf of vectors (say s1 and s2) on the same figire with R. plot function draws a new plot and there is no function like points or lines to draw a second ecdf on the figure.

Hi, I have a question for the group, perhaps someone can help me figure this out. I've already looked in the help files and they were no help to me. I have a vector of values and I am plotting an ecdf graph. 1. How can i draw a continuous line through the ecdf points? (lines and type for the plot with an ecdf object does not work) 2. Supposing I have this line drawn. I can add a
