Hey again, I didn't wat questions to get mangled up, so here's my second email. In matlab, there is the simple possibility to access colums x till last of a matrix using mydata(1:3, 5:end). In R, I so far use mydata[1:3, 5:ncol(mydata)] Is there a faster way? (in terms of typing) Thanks ahead, Berry ------------------------------------- Berry Boessenkool University of Potsdam,

Hi List, I have a raster and a polygon with attribute ID and Class. I want to have the fraction of each class present in each pixel of raster. I have use the raster::extract to get the value and weights as below. ex<-extract(raster,polygon,weighted=TRUE) this gives me [[1]] value weight 13943 0.24 13958 0.02 13959 0.84 13960 0.19 13987 0.03 13988 0.31 13990 0.30 [[2]]

Hi, I have to read in data which looks like this: SeriesA, 5, 5, 5, 5 SeriesB, 8, 5, 8, 8, 7, 10, 2, 7, 3 SeriesC, 5, 5, 8, 4, 7, 7, 4, 5 SeriesD, 5, 9, 5, 4, 2, 3, 10, 1 SeriesE, 7, 10, 9, 5, 8, 6, 10, 9, 5, 10, 4, 3, 2, 10, 8, 8, 10, 10, 10 SeriesF, 1, 2, 1, 5, 1, 7, 5, 7, 7, 3 There are actually much more data points in the data, each line contains between 300 and 500 values. If I use

I have a huge matrix and need to delete certain rows. What I need to do is: 1.In each row, calculate the sum of jth column and (J+2)th column 2. If the sum is greater than 2 then that row needs to be deleted. I have a sample matrix and my codes here. It does remove some rows but when it does, it skips the next row and each time it deletes a row, the dimension changes so it gets out of bound. I

Hi there, b is my dataframe. I have a dataframe. I am trying to get rid of the -INF values but didnt have much luck b[which(is.finite(b))] I can get rid of it for a single column b[,1][which(is.finite(b[,2]))] but not for all dataframe I used it inside of a sapply but still no dice my guess is it might have some differing row numbers and just ignoring the columns itself. Thanks Ramya

Dear all, I apologize if my question is quite simple. I have a dataset (20 columns & 1000 rows) which some of columns have the same value and the others have different values. Here are some piece of my dataset: obj <- cbind(c(1,1,1,4,0,0,1,4,-1), c(0,1,1,4,1,0,1,4,-1), c(1,1,1,4,2,0,1,4,-1), c(1,1,1,4,3,0,1,4,-1), c(1,1,1,4,6,0,1,5,-1),

Hello, I'm trying to set up the flowwing data structure in R: A data frame with 7,000 rows and 4 colums. The rownames have some special meaning (they are names of genes). The 1st column per row is itself a data frame, and columns 2 to 4 will keep numeric values. The data frame contained in the 1st column will have 54 rows (with special names) and 4 colums (1st col is a response, cols 2- 4

Hello, I've a data frame with 15 colums and 6000 rows, and I need the data in a single vector of size 90000 for ttest. Is there such a conversion function in R, or would I have to write my own loop over the colums? thanks for your help + kind regards Arne

Hi, I have the following problem: I have a data.frame with 36 sample sites (colums) for which I have covariates in 3 categories: Area, Month and River. Each Area consists of 3 rivers, which were sampled over 3 month. Now I want to fuse River 1-3 for one area in one month. To get a data.frame with 12 colums. I am trying to do a "for loop" (which may be a complicated solution, but I

Hi, I need some help to export a data frame with 83 rows and 1411 colums. I have used the package RODBC until now. But now, I have 1411 colums that I can't send to the old excel.

My name is Michela Marignani and I'm an ecologist trying to solve a problem linked to knight' s tour algorithm. I need a program to create random matrices with presence/absence (i.e. 1,0 values), with defined colums and rows sums, to create null models for statistical comparison of species distribution phenomena. I've seen on the web many solutions of the problem, but none provides

Hi, I''ve set up a bridge which connects two parts of the same subnet with each other. I''ve set up everything as described in the Documentation and it works very nicely. However: I have a problem with adding hosts to zones dynamically. The zone I want to add hosts to is called ''work''. Since only the bridge br0 is defined in /etc/shorewall/interfaces

Hello, I am a new user of R and I am trying to use the data I am reading from a spreadsheet. I installed the xlsReadWrite package and I am able to read data from this files, but how can I assign the colums into values? E.g: as I read a spreadsheet like this one: A B 1 2 4 9 I manually assign the values: A<-c(1,4) B<-c(2,9) to plot it on a graph: plot(A,B) or make histograms: hist(A) But

Hi, it seems not to be possible to add more than one host at once to a zone. So shorewall add br0:eth0:192.168.2.10,eth0:192.168.2.11 work fails, since "br0:eth0:192.168.2.10,eth0" is interpreted as one interface. --snip -- iptables v1.2.9: interface name `eth0:192.168.2.10,eth0'' must be shorter than IFNAMSIZ (15) Try `iptables -h'' or ''iptables

Hello, I'm new to R but wan't to use it to compute the statistics of my medical study. The study includes several parameters for a number of patients.

Hello all R user, I am very new with r I have been wondering whether anyone could help me. I have a 23000 row and 273 colums. What I want to do is to calculate unit vector for every 3 colums along the row. Could you please advise me how to do that using R? with regards, Abu _________________________________________________________________ 100?s of Music vouchers to be won with MSN Music

Dear List, somebody knows, if the following operation can be done in an easier way?
