similar to: In-string variable/symbol substitution: What formats/syntax is out there?

Currently in R, constructing a string containing values of variables is done using 'paste' and can be an error-prone and traumatic experience. For example, when constructing a db query we have to write, paste("SELECT " value " FROM table where date ='",cdate,"'") we are getting null result from it, because without (forgotten...)

Hi, I am a newbie in R and was working on some DNA data represented as strings of A,C,T and G (also wild-character like M and X). I use the Bioconductor package in R. Currently I need to convert a string of the form "ACCTGMX" to "1223400" i.e. A is replaced by 1, C with 2, T with 3, G with 4 and any other character with a 0. I checked with 'replace' and also with a

gsubfn is a package with one function, gsubfn, that is like gsub except instead of taking a replacement string it takes a replacement function. For each match, that match is passed to the replacement function along with the backreferences, if any, and replaced with the output of the function. If the first two arguments are omitted the defaults are set to do perl-style (sort of) string

The main goal of these patch series is to implement a new API that allows to retrieve created device-mapper devices for volumes and partitions back after they have been created. As part of this patch: - required libdevmapper version was bumped to 1.02. I think it is safe because it was released more then 10 years ago; - newer version of libdevmapper allowed to simplify code base a little bit; -

v1 was here: https://www.redhat.com/archives/libguestfs/2018-May/msg00058.html v2: - more correct explanation of a crash reason.

Hello; I am a R newbie and would like to know correct and efficient method for doing string replacement. I have a large data set, where I want to replace character "M", "b", and "K" (currency in Million, Billion and K) to millions. That is 209.7B with (209.7 * 10e6) and 100.00K with (100.00 *1/100) and etc.. d <- c("120.0M", "11.01m",

Hi, I don't know what I am doing wrong to the toupper does not seem working in sub + regex. The following returns 's' not the upper class 'S' as I expect: sub("q_([a-z])[a-zA-Z]*",toupper('\\1'),"q_sviRaw") Can someone tell me where I did wrong? Thanks, Richard [[alternative HTML version deleted]]

Hello, The code below works fine up until I try to use the "IN" statement in the last line. The proper SQL format is: SELECT * FROM this_table WHERE this_column IN (1,2,3,4,5) But, I think I may be getting something like: SELECT * FROM this_table WHERE this_column IN c(1,2,3,4,5) Which makes no sense in SQL. I think it may be just a matter of string massaging, but I'm not

Dear All, When one loads certain packages, some other dependent packages are loaded as well. Is there some way of detaching them automatically when one detaches the first package loaded? For instance, > library(sqldf) Loading required package: RSQLite Loading required package: DBI Loading required package: gsubfn Loading required package: proto but > detach(package:sqldf) > >

I have had some comments on sqldf regarding its dependence on tcltk such as the second last sentence on this blog post: http://translate.google.com/translate?hl=en&sl=zh-CN&u=http://www.wentrue.net/blog/%3Fp%3D453&prev=http://blogsearch.google.com/blogsearch%3Fhl%3Den%26ie%3DUTF-8%26q%3Dsqldf%26lr%3D%26sa%3DN%26start%3D10 sqldf does not directly use tcltk but it does use strapply in

Hi all, Does anyone have a version of strsplit that keeps the string that is split by. e.g. from x <- "A: 123 B: 456 C: 678" I'd like to get c("A:", "123 ", "B: ", "456 ", "C: ", 678) but strsplit(x, "[A-Z]+:") gives me c("", " 123 ", " 456 ", " 678") Any ideas? Thanks,

I have a text processing problem I'm hoping someone can help me solve. This issue it this. I have a character string in which I need to delete a variable number of characters from the string. The string itself contains the number of characters to be deleted. The number of characters to be deleted is proceeded by either a "+" or a "-". A toy example: Suppose I have

Hello, I have a dataframe (tab separated file) which looks like the example below - two values separated by a comma, and tab separation between each of these.
