Package: str2str 1.0.0

str2str: Convert R Objects from One Structure to Another

Offers a suite of functions for converting to and from (atomic) vectors, matrices, data.frames, and (3D+) arrays as well as lists of these objects. It is an alternative to the base R as.<str>.<method>() functions (e.g., as.data.frame.array()) that provides more useful and/or flexible restructuring of R objects. To do so, it only works with common structuring of R objects (e.g., data.frames with only atomic vector columns).

Add array slices to 3D+ Array '`abind<-`' adds array slices to arrays as a side effect. It used the function 'abind' in the 'abind' package. The purpose of the function is to replace the need to use ary2 <- abind(ary1, mat1); ary3 <- rbind(ary2, mat2); ary4 <- rbind(ary3, mat3), etc. It allows you to specify the dimension you wish to bind 'along' as well as the dimname you wish to bind 'after'. Unlike '`cbind<-`', '`rbind<-`', and '`append<-`', it does not have overwriting functionality (I could not figure out how to code that); therefore, if 'value' has some dimnames that are the same as those in 'a', it will NOT overwrite them and simply bind them to 'a', resulting in duplicate dimnames.abind<-
