IF/Else
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}}

vector comparison
...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 show("blah")
[1] "blah"
>
Only replace the numbers with for instance the vectors
> a = c("a")
> b = c("b","c")
> c = c("c","b")...

gsub patterns from vector elements w/out loop?
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 ( i in 1:length(x) ) {
y <- gsub(x[i],"something else",y)
}
Surely, there must be...

argh .. if/else .. why?
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.

parse error with if else (PR#9551)

Submission from: (NULL) (134.246.55.50)
the two following instructions provide a synthax error :

How "else" works
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...

if() command
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}
else {group == 3}
Syntax error
I know that is possible to find the solution by ifelse command or even
recode command, but I??d li...

R parser for If-else
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!)

applying a set of rules to each row
...The retirement
plan indicates what system the employee is enrolled under.
The data does contain a few other retirement plans, for now I want to
just ignore those plans. I have labeled plans as 1-CSRS and 2-FERS, and
3-Other. My first attempt at applying the rules was through a complex
nesting of ifelse statements, this was not very successful and quite
difficult to follow. I then wrote a function and tried using "apply"
unsuccessfully. The function is shown below.
I would like to put a short script or function together that would allow
for an efficient application of the rules to each...
