How is the relation between Frequency and Counts in hist/density defined?
Hi all, I'm looking to add a "density" smoother on top of a hist when Freq=T. In order to do this I can use the relation between count and density, but I would like to know if there is a way for me to predict it upfront. Here is an example: set.seed(242) z = rnorm(30) hist_z <- hist(z) hist_z$counts / hist_z$density # the relation is 15 # why is this 15 ?? # So I can now do:

R and .net/C#
Hi There, There seems to be a way for calling R from .net. However, is there anyway for calling .net/C# code from R? Something similar to the RJava package for .net? Thanks a mil!

table, sum, cat function
Hi, the second step in my exercice is to calculate the sum of the amout for each class et not the frequency i have this vector x           y 1          100 2          1500 3          3250 4          6250 5          2000 6           450 i want to use the function table and cat to calculate the sum of the amount in each class [0-1000], [1000-3000],[> 3000] Thank you for your help??

String search: Return "closest" match
Hi, I have to match names where names can be recorded with errors or additions. Now I am searching for a string search function which returns always the "closest" match. E.g. searching for "Washington" it should return only Washington but not Washington, D.C. But it also could be that the list contains only "Hamburg" but the record I am searching for is

horizontal boxplot + xlim
Hi there, I get a strange behaviour of a boxplot with the following code. There seems to be a problem with the xlim-parameter. Did I do anything wrong? What else can I do to force the boxplot to have a defined x-range? x <- rnorm(100) boxplot(x, notch=TRUE, xlab=parameter, xlim <- c(-4,4), horizontal = TRUE) Antje

C# DLL Library
Good afternoon everybody, I am sorry, this question might look trivial to some of you, but I read quite a lot of stuff about package creation and I would like a bit of you advices. I would like to develop a core library which I will be using both from R and from C#. I read that it was possible to import DLL to R. The thing is, I am not sure that the DLL created with C# will be compatible. I

excluding on element from a list
Dear List, I am making a list of all the files in a folder and I want to exclude one file called "proj.current". This is the 31st file in a folder. Currently I use the command: tdirs <- list.files(pattern="proj.")[-31] However I would like to exclude it based on its name and not the position. Any advice would be useful. Thanks, Daisy Daisy Englert Duursma Room

levels update
Hello, I hope this question is not too stupid. I would like to know how to update levels after subsetting data from a data.frame. df <- data.frame(factor(c("a","a","c","b","b")), c(4,5,6,7,8), c(9,1,2,3,4)) names(df) <- c("X1","X2","X3") my.sub <- subset(df, X1 == "a" | X1 == "b")

question mle again
A few day ago, I was looking for an answer to my question but didn't get one. Anybody who can help now? Hello, I tried to use mle to fit a distribution(zero-inflated negbin for count data). My call is very simple: mle(ll) ll() takes the three parameters, I'd like to be estimated (size, mu and prob). But within the ll() function I have to judge if the current parameter-set gives a nice

densities from a list with data.frames
Hi there, I have a list which consists of data frames (all data frames have the same amount and type of columns but different length). Now, I'd like to calculate for each data frame in the list the density function of the values of the fist column ($V1). This list could be an example: l <- list( data.frame(rnorm(100)), data.frame(rnorm(20)), data.frame(rnorm(200)) ) Can anybody help?

Legend and Main Title positioning
Hi folks, can anybody give me a hint how to solve the following problem? I have several plots in one window like this: layout(matrix(c(1,2,3,4), nrow = 2, byrow = TRUE)) plot(rnorm(100)) plot(rnorm(200)) plot(rnorm(300)) plot(rnorm(400)) Now, I'd like to create a legend below each plot and generate a common title. How can I do that? Antje

fitdistr question
Hello, I tried to fit a poisson distribution but looking at the function fitdistr() it does not optimize lambda but simply estimates the mean of the data and returns it as lambda. I'm a bit confused because I was expecting an optimization of this parameter to gain a good fit... If I would use mle() of stats4 package or mle2() of bbmle package, I would have to write the function by myself

Console output
Hi there, I though there has been a possibility to force the output on the console with one element per line. Instead of this: > 1:10 [1] 1 2 3 4 5 6 7 8 9 10 something like this > 1:10 [1] 1 [2] 2 [3] 3 [4] 4 [5] 5 [6] 6 [7] 7 [8] 8 [9] 9 [10] 10 Can anybody help? Antje

another histogram question
Hi there, I hope this question is not as stupid as the one before ... I tried to shorten my histogram (because the distribution is quite skewed and I simply don't want to see the long tail but still use the histogram plot). How can I do something like this? (The example does not work but I don't know why...) data <- rnorm(100) # as example, of course this is not skewed... h <-
