Hi I am a new user of R, and doing clustering analysis (dendrogram). I am quite interested in pvclust package because of facility of AU probability of each cluster. Now, i have a problem when handling large data set. I have data set of 183 rows and 5546 columns, and interested to make clustering based on bootstrapping but it says "Error in vector size capacity of 113.5 Mb". I could not understand this problem. Does any body have ideas regarding this problem ? How to solve it ? I will be greateful to you. Hopeful to your cooperation.
