str2str-package Structure to Structure
a2d (3D+) Array to Data-Frame

a2v (3D+) Array to (Atomic) Vector
abind<- 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.
all_diff Test if All Elements are Different
all_same Test if All Elements are the Same
append<- Add Elements to Vectors
cat0 Concatenate and Print with No Separator
cbind<- Add Columns to Data Objects
cbind_fill Bind DataFrames Along Columns - Filling in Missing Rows with NA
cbind_fill_matrix Bind Matrices Along Columns - Filling in Missing Rows with NA
codes Integer Codes of Factor Levels

dimlabels<- Add Elements to Vectors
e2l Environment to List
fct2v Factor to (Atomic) Vector
grab '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.
