[R] Problem about trim the space and add space to force the same nchar

[ken_lee]

Dear all,
     First, Can I trim the space like a<-"abc     "   ==>  a<- "abc"    or a<-"a  b  c       "   ==>  a<-"a  b  c"
     Second, Can I  generate a vector has the same length (nchar) like a<-c("mean  =10   ",
                                                                                                                                      "std       =1.23",
                                                                                                                                      "...


Best regards

Ken
