similar to: write table and dinnames

Hi I would like to shorten mod1 <- nls(ColName2 ~ ColName1, data = table, ...) mod2 <- nls(ColName3 ~ ColName1, data = table, ...) mod3 <- nls(ColName4 ~ ColName1, data = table, ...) ... is there something like cols = c(ColName2,ColName3,ColName4,...) for i in ... mod[i-1] <- nls(ColName[i] ~ ColName1, data = table, ...) I am looking forward to help Christof

I have a table: C1 RowName1 3 RowName2 2 and another table: C2 RowName1 5.6 RowName1a 4.3 RowName2 NA I want to join join the tables with matching rows: C1 C2 RowName1 3 5.6 RowName2 2 NA I'm thinking of something like:

Dear Group! I asked write.table to change the decimal point from "." to "," , but apparently it would only do so if the object to be written does not contain any character elements. I would like to understand, why this has to be so and - of course - find a solution for my matrix object jjmat, that I tried to write out by write.table(jjmat, file="jjmat.txt",

I await Luke''s node settings implementation with interest. At the moment however, I have this sort of ugliness: $site = $hostname ? { fred => "opsera", barney => "bedrock", default => "unknown site", ... } So I''ve knocked up this little function to use CSV files instead. Now I can just do: $site =

Hi, Could you please advice some easy way to do the following for a dataframe (header=F) having unequal column- & row- length. 1.

Dear R-users, is there some way how to pass various colnames to the following code for sorting data.frames? mydf.ordered<-with(mydf, mydf[order(colname1,colname2, colnameX, decreasing = TRUE), ]) I was trying something like Afunction<-function (mydf,colnames,decreasing=T){ mydf.ordered<-with(mydf, mydf[order(colnames, decreasing = decreasing), ]) } but it didnt work please

I don't see where describes the implementation of '[]'. For example, if x is a matrix or a data.frame, how the lookup of 'colname1' is x[, 'colname1'] executed. Does R perform a lookup in the a hash of the colnames? Is the reference O(1) or O(n), where n is the second dim of x?

Hy all, I apologize i've used rownames instead of colnames in my first exemple. (that's why i changed the mail object) I was on mars when i wrote my question... Every answer where correct ... but, because i've made a wrong question, people wern't able to understand... So finally i'm speaking about colnames : Let's be more precise: I've got a query that gives me for

I´m trying to connect my local network to the internet using 2 ADSL connections, very similar to what is discussed here: http://lartc.org/howto/lartc.rpdb.multiple-links.html but i have some differences: - i will use 2 identical ADSL connections from the same provider with 600 kbits download / 300 kbits upload each - i will have 2 dynamically allocated adresses (from the same range cause its the

Hi everyone, as what I''ve learned form this link<http://wiki.xensource.com/xenwiki/blktap>, i know that when i specify tap:aio I’m actually using the blktap driver and finally using "tapdisk" to wirite to raw image file. but the truth is even when i delete /usr/sbin/tapdisk the domU can still boot on my machine with tap:aio protocol after a deeper look into the scene,
