"&&" seems to behave strangely and gives different results from "&" e.g. in a data frame selection (regardless whether terms are bracketed)? ===========Script======================= test=data.frame(gender=c("F","M","M","F","F"),side=c("R","L","R","L","R")) test

Dear All, Is there a conmand to calculate the multiplication of the elements in a vector? For example: a=c(1,2,3,4) I want to get 1*2*3*4=24. Because the dimension of the vector is high, I want to know there is a command for this task in R? Thank you so much!

Hi there, I want to integrate a function over an irregular polygon. Is there any function which can implement this easily? Otherwise, I am thinking of divide the polygon into very small rectangles and use "adapt" to approximate it. Do you have any suggestions to get the fine division? Any advice is appreciated. Haiyong

Hello Listers, I am trying to sample a vector to create a new one of sample length, witha sum equal to the sum of the initial vector: initial = 10, 30, 10 (sum=50) sample example = 5, 35, 10 (sum=50) or 25, 15, 10 (sum=50), etc ... My problem is to control the sum, so it stays constant. Any suggestions would be very helpful ! Thank you in advance, Eric
