Hi, I have a column of data with repeated as mentioned below. *column_name* Acer Lenova HP Lenova Acer Acer Lenova I need to populate this column in a combo box without repeated data as mentioned below *combo box* Acer Lenova HP I tried as <%= collection_select(:column_name, TableName.all)%> "table_names" is a table and "column_name" is a column needed to

Hi, How can I use a substring match as a condition in a subset command? Sth like this: subset(input, field1=="blah1" & field2=="blah2") # but now with substring match in field2 subset(input, field1=="blah1" & field3 *substringmatch* "blah3") I've tried with gsub, but it won't work: subset(input, field1=="blah1" &

Hello, all. I found that so many unnessary queue files are saved at /var/spool/clientmqueue/ directory. I tested two way to delete these files. 1. # rm -rf /var/spool/clientmqueue/* 2. # cd /var/spool/clientmqueue/ ; find . | xargs rm -fv But this makes a few load of the system and took too much time to delete. What is the best way to delete fast without too much load?

I need to create a legend for a simple scatter plot in the following format. This is Blah1 number1 number2 This is Blah2 number3 number4 . . . This is Blah6 number11 number12 I looked up these help pages and found the following solution. lStr<-c(Blah1, Blah2,....Blah6, number 1, number2, ...number12) legend(x="topright",lStr,ncol=3) So this creates the tabular format I am

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a rectangular matrix of size 920 by 85. I'd like to coerce it into a square matrix such that all row/col names are present in the new matrix and the additional values are zero. As an example: A B C D A 1 2 3 4 E 5 6 7 8 F 9 10 11 12 Would be coerced to: A B C D E F A 1 2 3 4 5 9 B 2 0 0 0 6 10 C 3 0 0

folks, if i have three matrices, a, b, cc with some colnames in common, and i want to create a matrix which consists of the common columns added up, and the other columns tacked on, what's a good way to do it? i've got the following roundabout code for two matrices, but if the number of matrices increases, then i'm a bit stymied. > a <- matrix(1:20,ncol=4); colnames(a) <-

I have a machine with two swap partitions (sda2 and sda8). Both will have none as mount point. When I try to use puppet (using mount type) for managing fstab I get problems because "name" in both instances (i.e. mount path) will be "none". How should I fix this within puppet? Regards Halvard Moe

Hi Is there any way to position a key (legend) outside the plot area? i.e. in the margin between plot area and page margin. I realise I could achieve the same effect by creating a larger plot but not printing the axes and then draw the smaller axes independantly leaving room for the key. However, that wont work very well in my particular case. Thanks in advance Jeremy

To creat a series of plots I've constructed the following, however this doesn't work because the colnames being feed into n are embraced by quotes which is stuffing up the plotting function. Is there a way to suppress to quotes? coercion in to a different format?? for (n in colnames(tt[7:36])) { par(ask=T) attach(tt) plot(july~n) ... }

Hi again, another problem: This (below) isn't working and as far as I can see it damn well should. What I'm trying to acomplish is to run several data sets through the same graphing procedure, but for the pH data use a log y axis. using this code all graphs are drawn with a linear axis. Surely I should be able to set the ylog option to T using another object (logaxis). for (n in

Update: I have observed that stringi::stri_sub is linear time complexity, and it computes the same thing as base::substring. figure https://github.com/tdhock/namedCapture-article/blob/master/figure-substring-bug.png source: https://github.com/tdhock/namedCapture-article/blob/master/figure-substring-bug.R To me this is a clear indication of a bug in substring, but again it would be nice to have

Hi All, I'm looking for a way to get many substrings from a longer string and then stitch them together. But, since the longer string is really, really long (like 250 MB long), I don't want to do this in a loop and load and re-load the longer string many times. Does anybody have an idea? Maybe I could pass in two vectors (the first would have the starting coordinates, and the second

Hello together, I'm looking for advice on how to do some tests on strings. What I want to do is the following: (just an example, real strings/sequence are about 200-400 characters long) given set of Strings: String1 abcdefgh String2 bcdefgop use a sliding window of size x to create an vector of all subsequences of size x found in the set (order matters! ). Now create, for every string

Hi all, (and especially hi to Tomas Kalibera who accepted my patch sent yesterday) I believe that I have found another bug, this time in the substring function. The use case that I am concerned with is when there is a single (character scalar) text/subject, and many substrings to extract. For example substring("AAAA", 1:4, 1:4) or more generally, N=1000

Hi, I'm just coming to grips with "for" looping etc. and have a bit of a problem: I want to generate a sequence which goes 1 2 3 4 5 6 7 8 14 15 16 17 18 19 20 21 26 27 ... i.e. 8 consecutive numbers then 5 missed then the next 8 numbers etc. I was going to do this using the seq() function but couldn't figure out how so I thought I'd try a loop: for (x in seq(1,650,13)) {

Hello, Is there a function for searching a string for a given character? For example, I have transcriptions like tsibi tSibi tibi kibi I want to search the character object for the presence of 's' or 'S' or 'k'. I thought perhaps pmatch(c("k", "S", "s"), x) would work for me, but it wants to compare from the start of the string and returns

Currently as the first column in a data frame I have string values in the format xx_yy - I want to create a new column with just the substring xx (for each row in turn). Three possible ways to do this might be (1) split the string by '_' using strsplit and paste the first of the resulting variables into a new column, but I have been unable to do this for each row of my data frame in turn
