str2str (version 1.0.0)

Convert R Objects from One Structure to Another

Description

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..() 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).

Test for a POSIXct object

grab extracts the contents of objects in an environment based on their object names as a character vector. The object contents are stored to a list where the names are the object names.

Add Elements to Vectors

Dimension labels (i.e., names of dimnames)

Test for a Date object

Elements Inbetween Values Within a (Atomic) Vector

Environment to List

Test for an Atomic Vector

(3D) Array to List of Matrices

3D Array to List of Data-Frames

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.
