Hi R user, Can we calculate sample size when only mean and SE are given? Let say one example, I have mean with SE is 0.54+-0.0517 (mean+-SE). Is there any way to find the samples (sample size n) in that condition in R? i think this question is not related to R, I hope you won't mind. Thanks [[alternative HTML version deleted]]

I have a data frame (daf1), that holds +80000 records, and 10 variables (i.e. 10 columns and some 80000 rows) > length(daf1) [1] 10 > length(daf1[,1]) [1] 83805 I would like to sample() e.g. 10000 records from this. I use: > daf2 <- sample(daf1, 1000, replace = FALSE, prob = NULL) Error in `[.data.frame`(x, .Internal(sample(length(x), size, replace, : cannot take a sample larger

...he input from a mircophone as a byte-array stream in VC++ ?? So that i can encode it with speex an send it away. The second thing is, to decode the speex frame and play it on the speakers. It would be helpfull if you can give me a link to a site which explains this topic an include some littel code sampels. Thanks.

I tried to fit data with the following function: fit<-nls(y~ Is*(1-exp(-l*x))+Iph,start=list(Is=-2e-5,l=2.3,Iph=-0.3 ),control=list(maxiter=500,minFactor=1/10000,tol=10e-05),trace=TRUE) But I get only a singular Gradient warning... the data can by found attached(there are two sampels of data col 1/2 and 3/4). I tried to fix it by chanching the start parameters but that didn't solve the problem. Would it be a possibiliti to use the selfstart Model? How? Thanks for any answers This

Howdy, I just gem unpacked merb and have configured the sample_app to use an sqlite3 database. I see that the Rakefile has a task named "schema", but it points to /dist/schema/schema1.rb", which doesn''t exist. I copied /dist/schema/schema1.rb to /dist/schema/schema.rb then ran "rake schema". What''s the recommended way to create the database tables?

Hi, I am working with libspeex api. I would like compare the size of speex file encoded with libspeex and the size of speex file encoded with speexenc. For example, I encode with speexenc (narrowband, quality 1) a wav file of 1.43 MB (17 seconds) output a spx file weight 21KB, for other hand I encode with libspeex the same wav file with same characteristics in arm processor, pocket pc and the

Hi, I'm using the package quadprog to solve the following quadratic programming problem. I want to minimize the function (b_1-b_2)^2+(b_3-b_4)^2 by the following constraints b_i, i=1,...,4: b_1+b_3=1 b_2+b_4=1 0.1<=b_1<=0.2 0.2<=b_2<=0.4 0.8<=b_3<=0.9 0.6<=b_4<=0.8 In my opinion the solution should be b_1=b_2=0.2 und b_3=b_4=0.8. Unfortunately R doesn't find

In the tar-ball with the source is a lot of documentation. Probably read UNIX_INSTALL.txt. Lock at the sampels for smb.conf. Read the man pages. Personaly I recommend everybody to read man smb.conf form the fist to the last line.
