Hi Vijayan, one way going about it *could* be this: library(dplyr) library(tidyr) library(purrr) ex_dat <- c("FName: fname1", "Fval: Fval1.name1", "Fval: ", "FName: fname2", "Fval: Fval2.name2", "FName: fname3") data.frame(x = ex_dat) %>% separate(x, c("F1", "F2"), sep = ": ") %>% filter(F2

Using Ulrik?s example data (and assuming I understand what is wanted), here is what I would do: ex.dat <- c("FName: fname1", "Fval: Fval1.name1", "Fval: ", "FName: fname2", "Fval: Fval2.name2", "FName: fname3") tst <- data.frame(x = ex.dat, stringsAsFactors=FALSE) sp <- strsplit(tst$x, ':', fixed=TRUE) chk <-

@Don your solution does not solve Vijayan's scenario 2. I used spread and gather for that. An alternative solution to insert mising Fval - picking up with Don's newtst - is newtst <- c("FName: fname1", "Fval: Fval1.name1", "FName: fname2", "Fval: Fval2.name2", "FName: fname3", "FName: fname4", "Fval: fval4.fname4")

I have an HTML form on the screen, that is connected to a database (standard Ruby way). I found that there are people that would rather not fill in this information, but would rather search Amazon for the info. Therefore, I added a link to the right of one of the fields that, when pressed, will search Amazon for what ever you typed into that field. So, how can I do that? At first I tried

I probably shouldn't even comment, as I know so little about LLVM. But I've hand-written a couple kLOC of IR now and am starting to get a feel for the

Hello, i try to validate with JS if a Formfield has been filled with data. Usually I use "onsubmit()" in the form. My Code is <%= start_form_tag :action => ''update'', :id => @person.id, "onsubmit"=>"return isDateSet(document.forms[0].elements[''fieldname''].value)"; %> The JS-function returns false if length of

I'm communicating a softphone (SJPhone) to a Grandstream phone GXP-2000. The codec order on each one is the next: SJPhone: GSM - iLBC - PCMA - PCMU GXP2000: G729 - GSM - PCMA - PCMU (I have a G729 license, so there's no problem with transcoding G729) In my sip.conf, I've defined the following codec order: disallow=all allow=g729 allow=gsm allow=g726 allow=alaw allow=ulaw And my

I'm new to asterisk and need some help with getting a SIP connection working. I am trying to establish a termination point/DID number in another country. I am currently running Asterisk CVS-HEAD. My foreign provider uses SIP and authenticates via IP address. I am not required to register my SIP connection in order to send or receive calls. Can someone help me with how to understand the

Hi, I am trying to find a simple way to numerically solve a system of two equations equal to zero with two unknowns (x_loc and y_loc). Here is a mock data set and below it, the equations I need to solve. theta<-c(180,135,90)/(2*pi) x<-c(0,0,15) y<-c(20,0,0) 0 = -sum((y_loc-y)*(sin(theta)*(x_loc-x)-cos(theta)*(y_loc-y))/(((x_loc-x)^2+(y_loc-y)^2)^0.5)^3) 0 =

I''ve read the Rails Envy AAF tutorial at http://railsenvy.com/2007/2/19/acts-as-ferret-tutorial and its given me some really good ideas. My problem lies in having AAF search the target Model''s child tables. I have no problem at all doing something like: acts_as_ferret :fields => [:title, :update_collection, :member_name] def member_name return

Hi r-users,   I have the following code to solve 4 simultaneous eqns with 4 unknowns using newton iteration method.  But I got the error message:   pars <- c(1.15, 40, 50, 0.78) newton.input2 <- function(pars) {  ## parameters to estimate      alp <- pars[1]    b1  <- pars[2]     b2  <- pars[3]    rho <- pars[4]   f1 <- pars[1]*pars[2] f2 <-

I''m seeing this same problem that Josh was seeing back on March 23rd (see below) I''ve got the following YAML snippet stored in a text field: "--- !ruby/object:FieldValue \nattributes: \n item_id: 60\n title: Test\n field_id: 15\n created_by_id: 5\n locale: en\n link: www.cclearn.com\n comment: this is a test\n created_at: 2006-05-02 15:43:14.256792 Z\nnew_record:

Hi how can I validate a field only if another field is set to a specific value? I tried to use validates_length_of :fieldname, :maximum => 100, :if => :otherfieldname == ''myvalue'' But doesn''t work Thanks Paolo

Hi R-users, Does R has a topic on newton's method? Thank you for the info.

Jakob, I think this exactly what's happening. I debugged the resolveReferences for the ADD down into the resolve of TSFlags. It calls VarInit::getFieldInit for the "Val" field of "foo". The code is: Init *VarInit::getFieldInit(Record &R, const RecordVal *RV, const std::string &FieldName) const { if (isa<RecordRecTy>(getType()))

Hi R-list, I am new to optimization in R and would appreciate help on the following question. I would like to minimize the following function using two constraints: ###### fn <- function(par,H,F){ fval <- 0.5 * t(par) %*% H %*% par + F%*% par fval } # matrix H is (n by k) # matrix F is (n by 1) # par is a (n by 1) set of weights # I need two constraints: # 1.
