[R] replacement has length zero. In addition: Warning message: In max(i) : no non-missing arguments to max; returning -Inf

Hi, Here is my data, the first 10 rows u=regCond_all[1:10,] dput(u) structure(c(999, 999, 999, 999, 999, 999, 999, 999, 999, 999, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 99, 1.9, 2, 1.97, 1.99, 1.83, 1.78, 1.6, 1.52, 1.52, 1.36, 10.53, 9.88, 9.88, 10.53,

Hi Yolande, What's index() ? I get ind - which.min( abs(index(regCond_all) - thisStamp )) Error in which.min(abs(index(regCond_all) - thisStamp)) : could not find function index There's probably an easier way to do whatever you're trying to accomplish, but I'm afraid I can't tell what that

After replacing it to u for(i in 1:dim(diveCond)[1]){ + thisStamp - as.POSIXct(strptime(diveCond$timestamp[i], %Y-%m-%d %H:%M:%S)) + ind - which.min( abs(index(u) - thisStamp )) + diveCond$r_wvht[i]- u$WVHT[ind] + diveCond$r_dpd[i]- u$DPD[ind] + diveCond$r_apt[i] - u$APD[ind] +

Yolande, Please send your message to the R-help email list too, not just to me. On Fri, Aug 3, 2012 at 4:28 PM, Yolande Tra yolande@gmail.com wrote: Here is the description I am trying to build the data diveCond from two datasets diveData_2008, diveData_2009 and RegCond_all. How would I

Re: [R] replacement has length zero. In addition: Warning message: In max(i) : no non-missing arguments to max; returning -Inf

When i == 10, what is ind? diveCond$r_apt[10] regCond_all$APD[ind] Providing a subset is unhelpful. I gave you explicit dput() code to use; that's how we need data to be provided. I've given you various suggestions; if you don't implement them then there's not much point in me trying to help.

This runs, so there must be something else going on that you haven't told us about. diveCond - structure(list(dive_id = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), timestamp = c(2008-08-06 08:49:00, 2008-08-06 10:03:00, 2008-08-06 10:25:00, 2008-08-08 09:42:00, 2008-08-08 10:53:00, 2008-08-08 12:42:00,
