matrix transpose and object name
hello, everybody,
i have several unresolved issues:
1. how to do a matrix transpose? i cant find how to do it in the
documentation.
2..suppose i have an object named as lm1 from linear regression, how could
i refer to it by paste("lm",1,sep="") ?
3. to save a matrix 100 x 30, how to have a text file with 100 lines and 30
cols, instead of stacking them?
thanks.
