Dear Sir

I am facing problem in using traceWminim() function for cluster analysis. A
sample of data frame that I am using is of the following form

       sitename     lat        long      elev     map
1             Dir      35.12   71.51     4675   1472.10
2        S.Sharif   34.44    72.21     3155   1051.70
3        Peshawar   34.01  71.35     1185  435.90
4           Kakul   34.11     73.15     4301  1330.17
5         Balakot   34.33    72.21      3214 1652.20

Sir when I used the above function for 2 clusters as
> traceWminim(atsite,2)
then the following error message appears
Error in if (min.traceW.2 > traceW.1) { : missing value where TRUE/FALSE
needed

Please provide your guidance

Thank You
