Hello R-users, I've got a huge table with about 20.00 rows and 50 columns. The table now has headers as Members1, Members2 etc. My data are 8 different individuals. And I've got a column with clusters. So each individual belongs to different clusters and can occurs multiple times within a cluster (that's the reason that there can be more than 8 members). I want a presence/ absence

Hello everybody, Can anyone tell me how I could analyze data that are at a contigency table form? I already found function cfa in the cfa package but I still don't understand how I could use this function in order to elaborate a contigency table. Every answer is welcome! --------------------------------- ÁðïêôÞóôå ôçí äùñåÜí óáò@yahoo.gr [[alternative HTML version deleted]]

Hoi All, I am trying to append collums to a data frame in a for loop. I read in tables, do some processing and then write the result to a data.frame. But, the thing I want is, that the results are appended to the data frame in stead of overwriting the results of the prevous table. It has to look something like this: After going trough the loop once: Array 1 1 2 3 4 5 After going

rails: hi guys, one problem makes me even crazy! I use ruby on rails and mysql, but the table''s collum names in the mysql database is mixed case, not only lower case. but I do have set the database lower_case_tablenames=1, but still, the ruby on rail can not access mysql by just lower case table collums. why?! help!

Hi all, I need some help using read.ftable to read a contingency table. My columns are organized as follows: order--family--species--location--number of individuals I couldn't figure out how to change the data on my text file to be imported into R; and after you do that, is it possible to convert the table into a data frame? Any tips would be greatly appreciatted! Thanks a lot, Naiara.

Dear all, I am trying to construct 25x31 different matrices of 2x2 dimension. Here is the problem: we have the following matrix matrix(c(54+s0, 43+s1, 56-s0, 67-s1), nrow=2, ncol=2, byrow=T) the values for s0 and s1 are c(0:24) and c(0:31), respectively. I wrote the following code without the desired results

im a begginer in RoR and am using rails 3.2.3 and ruby 1.8.7 This forum has helped me to progress but I''m confused by one thing. My app is supposed to allow seaching for results depending on the check boxes that are checked. In my case, when the user checks a determined facility and clicks "search" the corresponding hotels with only those facilities should be returned. I can

Good Afternoon, My name is Gabriel, I'm doing an analysis if there is increase or decrease in dependence on the mutated genes, using 3 or more genes using the fisher exact test.I performed with success an analysis for two genes using fisher.test( ). example of the 2x2 contigency table: Gene A mutated | Gene A normalGene B mutated| 26

Hello R users, I'm trying to replace numerical values in a datamatrix with strings. R does this except for numbers under 10000 starting with a 9 (eg 98, 970, 9504 etc). This is really weird and I wondered whether someone had encountered such a problem or knows the solution. I'm using the next script: test_1 <- read.table("5+ref_151111clusters3.csv", header = TRUE, sep =

Hi R-users, I am new to R environment.I want to carry out a correspondence analysis on a contigency table with 64 columns and 298 observation of Environmental data.In many cells of the contigency table the frequency is just the value '1'. I got the following error. > CAIV(Eplankton) Error in if (L[i, j] < 0) return("Table L must contain non-negative numbers") :

Hi, In Splus if I call the function crosstabs() the output is a contigency table; in each cell of the table is printed: N, N/RowTotal, N/ColTotal, N/Total. N is the number of observations in each cell. The same call to xtabs() in R will produce the contigency table but the only entry in each cell is N. How can I get the same relative frequencies that crosstabs() gives? Thanks, mike --

Hello, I've tried to analyze some data with a CMH test. My 3 dimensional contingency tables are 2x2xN where N is usually between 10 and 100. The problem is that there may be 2 strata with opposite counts (the 2x2 contigency table for these are reversed), producing opposite odds ratios that cancle out in the overall statistics. These opposite counts are very important for my analysis, since

Hi, I want to analyse a contigency table (3 x 12) with a fisher.test beacause there are cells that are less than 5. ?mmen Anken Baf Belchen H?chi Hof Porti R?m Schmutz Sch?n Sissa Tann class14 7 26 150 2 46 68 126 66 3 31 7 61 class24 7 6 55 5 49 71 93 90 1 18 16 79 class34 1 1 4 3 19 8 29 61

Dear all, I have the following data frame: V1 V2 aaa chr1 aaa chr2 aaa NM aaa QC aaa chr10 att NM att chr7 What I want to do is to count the string (V1). But the condition of counting is: if the V2 of the string is "NM" or "QC" then the count is not increased. Hence the contigency table will look like this: #tag count aaa 3 att 1 Is

Apologies for what might seem like an simple question. I have written a model which gives me a frequency distribution for a particular score within a set. What I now want to do is loop this so that I get many different frequency distributions and append them to a table with a collum which specifies which loop the frequency distribution is from. What I wantto end up with would look something like

Dear Group, I have a data frame like the following: x <- c("Mike","A",0.01) x1 <- c("Carl","A",0.2) x2 <- c("Gene","C",0.3) x3 <- c("James","A",-0.3) x4 <- c("Dough","B",0) xx <- rbind(x,x1,x2,x3,x4) colnames(xx)<-c("Name","Class","NES") xx

Hello, Is there a test for independence available based on a multidimensional contingency table? I've about 300 processes, and for each of them I get numbers for failures and successes. I've two or more conditions under which I test these processes. If I had just one process to test I could just perform a fisher or chisquare test on a 2x2 contigency table, like this: for one process:

Dear all, This question is partly statistics and partly R and I apologise in advance for my (usual) verbosity! My data is a little more complicated that this suggests, but essentially I have proportion data from different studies (id), each from a specific country and region of the World. I would like to examine the variables that affect the proportion, but these factors are hierarchical. In case
