CVS won't compile: res_odbc error
Hi there, admittedly this is a slightly aged RH system. ;-> Yet what I'd like to know is if this compile problem is clearly due to the gcc version, or if there is a way to solve the issue...? Cheers, Philipp [root@box src]# gcc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-112.7.2) [root@box src]# rpm -q unixODBC

Taking the min of each row in a matrix
Hi, I'm a new user. I've been reading through the manual and looking at various examples but am still trying to make sense of the most efficient ways to handle matrices of data. If I have a 2D matrix of data, how do I get the mean, min, max value of each row? I see the "mean" function on a matrix will give me averages by row, but min and max give me the value for the entire

Crosstabbing multiple response data
...ge than I have in use of R; the example in the posting guide was also more complex than I was ready for, I'm afraid.) Sample of some of my efforts: library(reshape) melt(ratings,id=c("id")) ds1 <- melt(ratings,id=c("id")) table(ds1$variable, ds1$variable) # returns only rowcounts, 3 along diagonal xtabs(formula = value ~ ds1$variable + ds1$variable , data=ds1) # returns only a single row of collapsed counts, appears to not allow 1 variable in multiple uses I suspect I am close, so any nudges in the right direction would be helpful. Thanks much, Michael PS: www.rseek.org...

dynamic tablenames
Hi List! May I tap into your combined common sense ? I have a legacy logging app that needs to be modernized. At the moment, Data is going to be stored in 5 tables, one table is going to contain more than 200 million and 2 others about 60 million rows. Mysql will be used, unless someone sees a major advantage in using something else (at the moment data is stored in a raw positioned file format,

hdf5 package segfault when processing large data
Hi there, I am currently working on something that uses hdf5 library. I think hdf5 is a great data format, I've used it somewhat extensively in python via PyTables. I was looking for something similar to that in R. The closest I can get is this library: hdf5. While it does not work the same way as PyTables did, but it's good enough to let them exchange data via hdf5 file. There is just 1

Delete Block of Rows
I am trying to delete a section of rows from a data frame (based on no condition). Lets say my data frame has 200 rows and I want to delete rows 1 through 25. How would I do this? I know x[ -1, ] deletes the first row (or any desired row). I tried using different variations of this, like x[ -c(1:25), ] but that didn't work. I also tried writting a few functions, for example: deleteRows

Updating a table with Ajax
I''ve been banging my head against the wall trying to update a table (add/delete rows) using Ajax. It seems simple enough but just doesn''t work for me. I can get it to work using DIVs instead of a table, but doing the layout with DIVs is much more cumbersome and I know it works for others with a table (though I haven''t been able to find an exact example code anywhere).

Any interest in "merge" and "by" implementations specifically for sorted data?
Hi Developers, I am looking for another new project to help me get more up to speed on R and to learn something outside of R internals. One recent R issue I have run into is finding a fast implementations of the equivalent to the following SAS code: /* MDPC is an integer sort key made from two integer columns */ MDPC = (MD * 100000) + PCO; /* sort the dataset by the key */ PROC SORT;
