Hello, We are having some strange issues with RODBC related to integer columns. Whenever we do a sql query the data in a integer column is 150 actual data points then 150 0's then 150 actual data points then 150 0's. However, our database actually has numbers where the 0's are filled in. Furthermore, other datatypes do not have this problem: double and varchar are correct and do not alternate to null. Also, if we increase the...

Window 7 R 2.15 I am writing a simulation which generates sample sized estimates from simulated data. When I run the function shown below, power.t.test(delta=14.02528,sd=1.945226,power=0.8,sig.level=0.05) I get an error message: > power.t.test(delta=14.02528,sd=1.945226,power=0.8,sig.level=0.05) Error in uniroot(function(n) eval(p.body) - power, c(2, 1e+07)) : f() values at end points not of opposite sign The fact that the function can not return...

We would like to have password history working in our setup which is samba with Sun Directory Services 7.0 on the backend. Everything else seems to be working ok, but I notice that the sambapasswordhistory entry for any particular user is filled with 0's. If I set the password for the account, then it's 16 0's, followed by a copy of the password hash, and the rest 0's. If I change the...

Hello everyone, I`m trying to normalize and analize an illumina SNP array. But when i`m trying to segmentate i`m getting an error: Error in sort(abs(diff(genomdat)))[1:n.keep] : only 0's may be mixed with negative subscripts. I`ve tried everything to fix this but the error still occours. Can anybody give me a tip? Thanks in advance! -- View this message in context: http://r.789695.n4.nabble.com/Error-in-sort-abs-diff-genomdat-1-n-keep-only-0-s-may-be-mixed-with-negative-s...

Hi all, I have a matrix with each column containing a large number of integers (0 and above). in each column beyond a certain row (say row 120 in column 1, row 134 in column 2, 142 in column 3...) there are only 0's. I want to find, for each column the row number of the last row which contains a positive integer beyond which there are 10 or more 0's. so in the followi...

Hi, I'm trying to do a non-metric multidimensional scaling using isoMDS. However, I have some '0' distances in my data, and I'm not sure how to deal with them. I'd rather not drop rows from the original data, as I am comparing several datasets (morphology and molecular data) for the same individuals, and it's interesting to see how much morphological variation can be associ...

Dear R users and developers After upgrading to Windows XP and R 1.9.1 and 2.0, I retried to execute plot.baysian() to a data set that I had used previously to plot with no problem in win2000 R1.8. The error I get is: Error in points(Mbar[-index], lods[-index], pch = ".") : only 0's may mix with negative subscripts Thanx in advance Dino P.S. I allre...

Hi, What's one way to convert an integer to a string with preceding 0's? such that '13' becomes '00000000013' to be put into a string I've tried formatC, but they removes all the zeros and replace it with blanks Thanks -- Regards, Anh Tran [[alternative HTML version deleted]]

I am trying to increment a filename in a script example name is 000001.txt and I need to keep the leading 0's. I have no problem if the name was 1.txt, 2.txt etc... var=`expr $var + 1` however how do I keep the leading 0's? Thanks, Jerry

...eturned values when there is no error message). Is this the intended behavior? I couldn't see any comments about zeros or negative values in matrix indices in either ?"[" or Section 3.4.2 "Indexing matrices and arrays" of the "R Language Definition" (Version 2.0.1), or in Section 5.3 "Index arrays" of "An Introduction to R" (Version 2.1.0). (It looks like the special treatment of zeros and negative indices is being applied to the vector indices after they are derived by standard indexing arithmetic from the matrix indices -- so zero...

I'm trying to calculate the percent change for a time-series variable. Basically the first several observations often look like this, x <- c(100, 0, 0, 150, 130, 0, 0, 200, 0) and then later in the life of the variable they're are generally no more 0's. So when I try to calculate the percent change from one observation to the next, I end up with a lot of NA/Nan/INF, and sometimes 0's which is what I want, in the beginning. I...

...n's MULCOX2, SAS, and S-plus. Is this the way to fit such a model in R? Suppose I have variables: time, delta, treatment, and surrogate. Should I repeat the dataset (2x) and stack, creating the variables: time1 (time repeated 2x), delta1 (delta repeated 2x), treatment1 (same as treatment, but 0's for the 2nd set), treatment2 (0's in first set, then same as treatment), and surrogate2 (0's in first set, then same as treatment), and id (label the subject, so each id should have 2 observations). Thus, a dataset with n observations will become 2n observations. To fit, do fit <...

Dear R helpers,   I have two queries.   (1) If the dataset contains some variables having all the entries = 0 and while analysing I want to delete those pericular columns, how do acheive this. i.e.   dataset1   sr_no    var1      var2       var3        var4        var5 1           5           0          3              1           0 2           3           0          2              9           0 3          ...

Okay, you've answered part of my question, which is "What value equals silence?". I assume then that a (decoded) frame of silence would be a buffer the size of my frame (320 bytes) full of 0's. Passing this frame (a frame of all 0's) through the encoder causes it to blowup though.. In response to your answer below, I don't think I want to overwrite the decoded audio output since I don't want to lose any "voice", I only want to interpo...

Hi, I cannot find a 'vectorized' solution to this 'for loop' kind of problem. Do you see a vectorized, fast-running solution? Objective: Take the value of X at each timepoint and calculate the corresponding value of Y. Leading 0's and all 1's for X are assigned to Y; otherwise Y is incremented by the number of 0's adjacent to the last 1. The frequency and distribution of X vary widely and may have ~100 repeated 0's or 1's in a vector of 10k timepoints. Example: time 1 2 3 4 5 6 7 8 9...

Dear List, I'm wondering if there is a better/cleaner/more efficient way of replacing 0 values in a variable with the minimum of the non-missing and non-zero values of that same variable, but doing it within the levels of a factor? Consider the dummy example data presented at the end of my message. Within each 'Site' there are some 0 values and possibly some NA's. I can c...

...e and using an unordered compare. Could someone look into this? While I'm at it, is there any reason why only the most significant bit of the return value of VFCmp is defined (according to the documentation)? Both AltiVec and SSE set the components of the result to either all 1's or all 0's. Having only the most significant bit doesn't seem useful to me at all, and (arithmetic) shifting vectors to replicate the bit isn't supported. Thanks!
