Hi, I am trying to write a package(A) for myself and need to use a function from another package(B) which is in R already(need to install it before use). Could anyone tell me how to implement that? Also I hope that my package gives an ERROR message(something like "STOP, please install package B first") if the package B is not installed yet. It is my first time to write a package. Thanks

Hi, Thanks for reading. I am running a process in R for microarray data analysis. RedHat Enterprise Linux 4, dual AMD CPU, 6G memory. However, the R process use only a total of <200M memory. And the CPU usage is total to ~110% for two. The program takes at least 2 weeks to run at the current speed. Is there some way we can increase the usage of CPUs and memories and speed up? Any
