similar to: Problem with parser and if/else

I am trying to do the simplest thing in the world. The following works: aaa <- ifelse(aaa==5, 6, 7) But if I want to change the if...else syntax instead, it gives errors and assigns 7 to aaa. Here is the problem code: aaa <- 5 if ( aaa==5 ) { aaa <- 6 } else { aaa <- 7 } Here is the output: > aaa <- 5 > if ( aaa==5

How could I check the value of an javascript object''s attribute? <div id="new_item_details" style="display:none"></div> <%= link_to_function("Show details...", nil, :id => "show_details") do |page| page.visual_effect(:toggle_blind, :new_item_details) if (page[:new_item_details].style.visibility ==

Under NT with 1.3.1 if (x == 1) { cat("Saw x=1\n"); } else { cat("Saw x!=1\n"); } works as expected, but if (x == 1) { cat("Saw x=1\n"); } else { cat("Saw x!=1\n"); } is currently giving me a syntax error on the "else" line. Apparently the parser considers the if statement to have ended as soon as it sees first closing brace, unless

Using Sweave in the tools library (R version 1.8.0: sorry i havent upgraded), it seems i cant use if statements in R chunks that make graphs. i have this: <<fig=TRUE,echo=F>>= par(mfrow=c(1,1)) if(exists("x")) plot(x,x) else{ plot(1,1,type="n") text(1,1,"data not available.\n") } @ and I get this error: Error: chunk 6 Error in parse(file, n,

Hello, I am doing a simple if else statement in R. But it always comes out error such as 'unexpected error' There are two variables. ini and b. when ini=1, a=3; when ini>1 and b>2, a=5; all other situations, a=6. I don't know where it is wrong. Here is my code ini=3 b=4 if (ini==1) { a=3 } else if (ini>1 and b>2 ) { a=5 } else {a=6} Thanks a

Dear All, I have these data: exampledata <- c("This is one item", "This is Another One", "And so is This") I would like to find each occurence of a blank space followed by a Capital Letter and replace it by a blank space, a left curly brace, the respective Capital Letter, and then a right curly brace. I thought the following will do: gsub(pattern = "

Re: placement of braces and "else" clauses. At the R prompt, I believe their placement must avoid causing a syntactically complete statement at the wrong place. This can results in what might be considered rather awkward looking code. IF it is known that code will be used via sourcing a script only, is there any potential problem with placing braces as shown below ? xxx <-

Dear R users, can anybody explain the reason, why the first piece of code below gives a parsing error, while the other two variations work? # Gives a parsing error x <- 1 if (x < 0) { y <- 1 } else # Error occurs at this line { y <- -1 } # This works x <- 1 { if (x < 0) { y <- 1 } else { y <- -1 } } # This works too x

Hi list, I don't know if somebody has spent a lot of time debugging strange problems with if else positioning - the parser seems to recognize only the syntax bellow - this is the only way of making these pieces of code to work. As far as i'm concerned, no examples were available (it would be so awesome to have them in the introductory manual!) #Try to change the placement of the

I have implemented this exact behavior in an out of tree LLVM fork I maintain, where one of my users needed this behavior, and it seems to work well. What we have done is extend the definition of DISubprogram to contain a new field "endLine" which holds the line number of the closing brace. A pass late in our backend uses this information to set the DebugLoc of return instructions in our

I just want to confirm but it seems that if-then-else is not permitted in case structure. It was not really documented but it seems to be the case. Can anyone confirm? switch(${DIALSTATUS}) { case NOANSWER: { // if-then-else not permitted If (${ael-var} = 1) { Playback(beep);

Perhaps most of you have already seen this? http://google-styleguide.googlecode.com/svn/trunk/google-r-style.html Comments/Critiques? Thanks, Esmail ps: Reminds me of PEP 8 for Python http://www.python.org/dev/peps/pep-0008/ Maybe not that surprising since Python is also one of the main languages used by Google.

hi, i lost half a day trying to figure out how r is parsing statements in multiple lines. can someone explain (or direct me to documentation) the following. consider the following statements in a program file, say foo.r: a <- 1 + 2; b <- {1 + 2}; {c <- 1 + 2}; d <- c(1, 2); if i do source("foo.r"), i get a=3, b=2, c=1, d={1,2}. according to the r language definition

Hey all, I get the following error. Now I know it''s related to a curly brace, but it seems that all curly braces are properly in place. So I''m not sure why I get this error: SyntaxError in DashboardController#panels rails/app/controllers/dashboard_controller.rb:170: syntax error, unexpected ''\n'', expecting tASSOC def panels addDetailToContainer =

Hi all! To add to my previous posting I want to give some more deatils give a more precise I want to print a hyphen to a pdf() or postscript() device. As the documentaion of postscript says ASCII Character 45("-") is mapped to a minus sign (ASCII Character 95) by default. The advice given is to use "\173" for a hyphen. But, the following code produces a curly brace instead

Simple Case: 1.int main() 2.{ 3. int i = 0; 4. return 0; 5.} compile command: clang -g a.c In LLVM IR, we have one attribute named "scopeLine" to indicate the left parentheses. But we don't have one attribute to indicate the right parentheses (line 5 in this example). So if we use gdb to debug it: (gdb) b main Breakpoint 1 at 0x100005c8: file a.c, line 3. (gdb) r Breakpoint

Hi everybody, I've found a very interesting problem in R: the if-else statement doesn't work in a main program. Sounds crazy, but true. I tried this very easy example, and I got syntax error at the "else" line. Example: ------- a <- 1 if ( a == 1 ) print("yes") else print("no") -------- I tried on Windows and on Linux, but none of them works.

Can somebody explain the problem in the following expression? Thank you /> if (species == 1){ + fitness <- (1-b)*exp(-((microsites-niche.preference)/(niche.width.specialist+a.specialist)^2)*(1-a.specialist) + }else Error: unexpected '}' in: " fitness <-

I was initially pretty shocked by the result in this question: https://stackoverflow.com/questions/57527434/when-do-i-need-parentheses-around-an-if-statement-to-control-the-sequence-of-a-f Briefly, the following returns 0, not 3 as might be expected: if (TRUE) { 0 } else { 2 } + 3 At first I thought it the question was simply one of syntax precedence, but I believe the result is too
