Hi, I am trying to write a for loop with if else statements to calculate biomass density estimates for different types of sampling gear. My code is: bmd=for (i in 1:length(Gear)){ if (Gear==20) {bioden=Biomass/141} else {if (Gear==23) {bioden=Biomass/68}} else {if (Gear==160) {bioden=Biomass/4120}} else {if (Gear==170) {bioden=Biomass/2210}} else {if (Gear==300)

What is wrong with the following? x <- 1:2 if(x[1] > 0) { if(x[2] > 0) { print("1 & 2 > 0") } else { print("1 > 0") } } else { if(x[2] > 0) {

I know this is fairly basic, but I must have somehow missed it in the manuals. I have two vectors, often of unequal length. I would like to compare them for identity. Order of elements do not matter, but they should contain the same. I.e: I want this kind of comparison: > if (1==1) show("yes") else show("blah") [1] "yes" > if (1==2) show("yes") else

Dear list, I have two vectors: x <- c("one","two") y <- paste(rep(x,2),"blah") I want to replace all occurrences of each element of x in y with something else, so that y looks like this: y [1] "something else blah" "something else blah" "something else blah" [4] "something else blah" I can do this using a loop: for (

Hello, would someone please help explain the following inconsistency in the if/else statement to me? The format of the if/else #3 below is ok, but if/else #1 is not? (I get an "unexpected else" type error.) In order for it to work I have to use if/else #2 Thanks .. maybe there is some reason for this, but this looks very inconsistent to me. R version 2.10.1 (2009-12-14) Ubuntu 9.04

Hello, This example seems strange to me: > if (2 > 3) print('Yes'); else print('No') Error: unexpected 'else' in " else" > {if (2 > 3) print('Yes'); else print('No')} Error: unexpected 'else' in "{if (2 > 3) print('Yes'); else" > { + if (2 > 3) print('no') + else print('yes') + }

Hey listers, I am trying to do something simple... Check the program below... I would like to create a variable named COLOR according to the conditions that I stablished... But the problem is that it seems that my variable COLOR is checking just on sample, may be last in the loop... Certainly, I am missing something... Thanks in advance, Marcio

Hello, I am getting an error with the following code: if( P2 > P1) + { + P<-P2 + } > else Erro: unexpected 'else' in "else" > { + P<-P1 + } I checked the syntax so I don?t understand, I have other if else statements with the same syntax working. Thanks in advance -- View this message in context:

Hello list, I have this strange problem whenever I try to make an "ael reload" from the Asterisk CLI. The command gives the following result and crashes: voip-1*CLI> ael reload Disconnected from Asterisk server Executing last minute cleanups Asterisk ending (0). root at voip-1:/etc/asterisk# As far as I can see, aelparse can't find any errors in my configuration, following

Dear R-users, I have a problem with the IF-ELSE syntax. Please look at the folllowing code and tell me what's wrong: a <- TRUE if ( a ) { cat("TRUE","\n") } else { cat("FALSE","\n") } If I try to execute with R I get: Error: syntax error, unexpected ELSE in "else" The strange thing is either "cat"

I have what is likely to be a simple question about the else keyword. The usage in the help pages is as follows: if(cond) cons.expr else alt.expr I would expect to be able to use it in the following way as well: if(cond){ cons.expr } else alt.expr This results a syntax error. Am I doing something wrong, or doesn't R support the spanning of the combination of if and else

Hi everyone ! Could you please help me with this problem ? I??ve trying to write a code that assign to a variable the content from another, but all I??ve got is a message error. For example: if (age <=10) {group == 1} else if (age > 10 & age <= 20) {group == 2} else {group == 3} Syntax error Or if (age <=10) {group == 1} else (age > 10 & age <= 20) {group == 2}

Hi this is my first post. I am trying to run a simulation for a computer playing Von Neumann poker and adjusting it's expectation of an opponent's behavior according to how the opponent plays. This program involves random generation of "hands" and shifting of parameters. However, when I run the code, no errors come up, but the program doesn't do anything. Could someone

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

All, I would like to apply a set of rules to each row of the sample data set below. The rule sets are the guidelines for determining an individual's date for retirement eligibility. The rules are found in this document, http://www.opm.gov/feddata/RetirementPaperFinal_v4.pdf. I am only interested in the top two categories for retirement eligibility, the CSRS and FERS plans. The data set has

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 r-help people, could you confirm that this is correct behaviour for R? I am using RH9. the code: x1 <- 1:6 t1 <- 5 if (length(x1) >= t1) { cat("in the if \n") } else { cat("in the else\n") } runs fine: > source("test_if_else.R") in the if > but the code: x1 <- 1:6 t1 <- 5 if (length(x1) >= t1) { cat("in the if 2\n") }

hello, I need help because I don't understand the syntaxe "else" how can I write it for example I writed a script to cut missings values and I have errors > if(na==length(C)){ + pos=match(0,match(donGeno[[na-1]],donGeno[[na]],nomatch=0)) + for(k in 1:(na-1)) { + if(pos==1) {donGeno[[k]] <-
