similar to: Reading data into R

I''m reading the Ruby on Rails book by the pragmatic programmers, and it has a brief section on using the _tag input fields (text_field_tag, etc) to collect form data for fields that don''t represent fields in a model. They do validation manually in the controller, which seems really clunky. Is there any way to normalize the form validation between model input fields and non-model

Hi all, I have found what I think it is a bug in DFAPacketizer::ReadTable. When finding NextStateInTable to cache all transitions belonging to a state into CachedTable, ReadTable does not check bounds: unsigned ThisState = DFAStateEntryTable[state]; | unsigned NextStateInTable = DFAStateEntryTable[state+1]; which makes NextStateInTable get a random value when state == <last state in

Hi Anshu, no, I did not fill a bug report. It is not so easy to make the code fail noticeably; during Hexagon CodeGen tests it happens silently and tests pass. I am working on another VLIW backend which uses DFAPacketizer and compiling llvm with gcc-4.4 makes it segfault, but with gcc-4.7 the bug gets hidden again (it still happens, but values after DFAStateEntryTable in memory are such that

Hi Carlos, Thanks for identifying the bug. I'll confirm and fix. Is there a bug report open for this? -Anshu --- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation On 12/10/2012 4:48 AM, Carlos Sánchez de La Lama wrote: > Hi all, > > I have found what I think it is a bug in DFAPacketizer::ReadTable. > > When finding

Carlos, I committed a fix in r169783. Thanks for catching this. However, I could not reproduce an invalid read or a segfault even with fadd.ll. Is there a test case you can check in that reproduces this bug? Even if the segfault occurs intermittently, that's better than no test case at all.

Hi Anshu, I got a testbench which fails (and segfaults) consistently with an environment (gcc + os) conveniently preserved in a virtual machine. I will confirm that it is gone there and report.

Hi, is there are reason for not supporting NULL or "NULL" values for argument colClasses in read.table(), much like you can use NULL values for argument 'what' in scan()? This would help quite a bit when reading large data files where only a few columns are of interest. I've modfied read.table() to so it calls scan(what=...) also with NULLs for the fields to be skipped.

You need admin assistance, someone will probably see your request here and fulfill it.

If read.csv's colClasses= argument is NOT used then read.csv accepts double quoted numerics: 1: > read.csv(stdin()) 0: A,B 1: "1",1 2: "2",2 3: A B 1 1 1 2 2 2 However, if colClasses is used then it seems that it does not: > read.csv(stdin(), colClasses = "numeric") 0: A,B 1: "1",1 2: "2",2 3: Error in scan(file, what, nmax, sep,

This has some nice properties: 1) It self-documents the input expectations in a similar manner to colClasses. 2) The implementation could eventually "push down" the coercion, e.g., calling it on each chunk of an iterative read operation. The implementation needs work though, and I'm not convinced that coercion failures should fallback gracefully to the default. Feature requests

Dear Rs: Hi, I am trying to read a big text file (nrows=243440, ncols=144). It seems the computational time of all the read methods (scan,readtable,read.delim) is not linear to the number of rows I want to read in: things became really slow once I tried to read in 100000 lines compare to 10000 lines). If I am reading the profiling result right, I guess scan wouldn't help either. My

Howdy, I'm working on reviving the debian packages. I haven't done debian packaging in a while, so I've put an alpha build of 1.3.8 on http://www.austinenglish.com/blah. Currently only squeeze/i386, but if these work well, and there is interest, I can do the other releases/64-bit versions. Please let me know if they do/don't work for you, or any other feedback. Cheers, Austin

It seems to me that colClasses = "logical" in read.table produces incorrect results when the input file has `1' and `0' in it. Although, it is perhaps just as likely that I am misunderstanding the documentation. Here is a simple example: > file.show("test.txt") x 1 0 1 > read.table("test.txt", header = TRUE) x 1 1 2 0 3 1 This result is fine. >

Hi, I am trying to write a function to automate multiple graph generation. My data looks like: Table of numeric values with the following headers: timeM1 statusM1 xM1 timeM2 statusM2 xM2 timeM3 statusM3 xM3 1 2 3 4 5 6 Where M1,M2, M3 hve no similarity except they have a max string length of 7.

Hi, having read "my job went to india" I decided to quit programming within the Microsoft environment and start something different...

Hello all, Can somebody point me to references or provide some code on dealing with this date issue. Basically, I have two vectors of values that represent dates. I want to convert these values into a date format and subtract the differences to show elapsed time in days. More specifically, here is the example: Date1 Date2 032398 061585 032398 061585 111694 101994 111694

Hi all, I have problems reading Unicode (UTF-16) coded tables in R 2.8.1 under Windows Vista. Imagine the following table: a b c d X 1,2 1,3 1,4 Y 2,2 2,3 2,4 Z 3,2 3,3 3,4 Usually I would use the following code to read the table: t = read.table("test.txt", header=T, sep="\t",dec=",") This works well if I create the table

PR43308 describes a case where StackProtector fails to protect against a fairly simple smash. This problem started after r363169, which removed StackProtector's own analysis function HasAddressTaken, and used CaptureTracking's PointerMayBeCaptured instead. The problem here is that "pointer is captured" and "pointer could be used to smash the stack" are not equivalent
