Re: [R] Error: missing value where TRUE/FALSE needed

[Fox, John]

Dear Shashi Seth,

The principal problem here is that the "argument" to if() must be logical, 
while comparing anything to NA always produces NA. The proper way to test for 
NA is with is.na(). 

There's potentially something more subtle going on here, however, which is that 
even if some of the elements of the logical expression in the "call" to if() 
are NA, the expression may evaluate to FALSE (but never to TRUE) if the non-NA 
elements imply that it is FALSE. Consider the following examples:

> TRUE && FALSE && NA  # FALSE regardless of the value of the last element
[1] FALSE

> TRUE && TRUE && NA  # truth depends on the value of the last element
[1] NA

> (TRUE && FALSE && NA) != NA
[1] NA

> (TRUE && TRUE && NA) != NA
[1] NA

> is.na(TRUE && FALSE && NA)
[1] FALSE

> is.na(TRUE && TRUE && NA)
[1] TRUE

I hope that this helps,
 John

Re: [R] Error: missing value where TRUE/FALSE needed

[Ulrik Stervbo]

Dear Shashi,

I don't see any code, but I will take a guess anyway:

The error tells you that you try to compare a boolean with something that
is not (TRUE or FALSE cannot be compared to NA).

[SHASHI SETH]

Hi, 



I am getting the following error:

Error in if ((sum > 0 && sums1 > 0 && sums2 > 0) != NA) { : 

missing value where TRUE/FALSE needed





I have including my code below for your review:

Re: [R] ERROR: missing value where TRUE/FALSE needed

[PIKAL Petr]

Hi

What is mctp?
Why do you think your data are well defined? Did you try str(Datos)?
Where you get this error? When you do call mctp or summary?

The main problem is that you do not follow posting guide, do not provide 
reproducible code and/or at least some info about your data. 

Without that I wonder if anybody can resolve your problem.

Regards
Petr

Re: [R] ERROR: missing value where TRUE/FALSE needed

[MacQueen, Don]

In addition to what Petr said,

That message most likely means that you have some missing data where
you're not allowed to have missing data in your Datos.

Look and see if the mctp() function has an argument that controls what it
does with missing data.

Re: [R] Error .. missing value where TRUE/FALSE needed

[jim holtman]

When the error occurs, valueDiff is NA:

Error in if ((seedCount = seedNumber)  (valueDiff  sup)) { :
  missing value where TRUE/FALSE needed
 valueDiff
[1] NA


Look at your loop; you are going through 100 times so on the last time
you are trying to access:  fcsPar[k+1] which is the 101th entry which
is NA.  Your program has a bug in it.

Re: [R] Error: missing value where TRUE/FALSE needed

[Benilton Carvalho]

make k = 100, note that you're doing fcsPar[k]-fcsPar[k+10]

note fcsPar has length 100...

therefore valueDiff becomes NA.. and the if() statement fails.
