Dear useRs, I would like to query an Access database through R based on a date attribute but, unfortunately, I fail to do so. For example, the table test_table of the test.mdb looks like: ID cd market competitor dd price 1 1 2007-11-20 atl-bos delta 2007-11-20 210 2 2 2007-11-20 atl-bos delta 2007-11-21 190 3 3 2007-11-20 atl-bos delta 2007-11-22

Hi, I have a test_table where the dim is 62220 by 73 (row by col) I would like to partition the rows into 170 equal parts (170 tables where each is of dim 366 by 73), and rearrange them horizontally. The source codes I have: for (i in 1:170) { c = cbind(c,test_table[(367*i+1):(367*(i+1)),2:73]); } Unfortunately, using for loop and cbind for a table of this size

It seems that Access needs that you surround the dates with a # symbol. You probably need something like. res <- sqlQuery(channel, "select * from test_table where market = 'atl-bos' and competitor = 'delta' and dd = #2007-11-20#") Hope this helps, Stefano -----Messaggio originale----- Da: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org]Per

Hi, table1D() below can be up to 60x faster than base::table() for the 1D case. Here are the detailed speedups compared to base::table(). o With a logical vector of length 5M: 11x faster (or more if 'useNA="always"') o With factor/integer/numeric/character of length 1M and 9 levels (or 9 distinct values for non-factors):

This idea is from ext4. By this patch, we can make the dio write parallel, and improve the performance. We needn''t worry about the race between dio write and truncate, because the truncate need wait untill all the dio write end. And we also needn''t worry about the race between dio write and punch hole, because we have extent lock to protect our operation. I ran fio to test the

Hi, am running: Redhat EL4.4 i386, Samba 3.0.23d from Sernet, ext3 fs Samba as PDC Someone's got the idea to have one big share with access managed by directory's sticky bit.

I''m looking to drive the development of a rails app that does nothing but serve a JSON API. All of the models are well tested elsewhere, so I needn''t worry about that. My only immediate goal is to be able to fire off requests to a path and check the returned JSON. I''ve tried a number of methods for this today, without being particularly enthused about any of them. I

Hi all, In re-doing the very first Hello World in the Agile Rails WEb Dev book, I continuously got blank pages, no matter what URL I put in, except when I put http://localhost:3000/ After eliminating everything else, I switched from Mozilla to Konqueror, and the symptom went away. I tried clearing cache on Mozilla, but that didn''t bring it back. I copied and pasted the URL from

So I''m updating multiple model objects in one go with something like this in my controller: => Photo.update(params[:photo].keys, params[:photo].values) When the update fails due to validation errors, how do I detect it? The Rails API says: "If the save fails under validations, the unsaved object is still returned." So I can''t simply do this: => if
