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).

rbind-set

Add Rows to Data Objects `rbind<-` adds rows to data objects as a side effect. The purpose of the function is to replace the need to use dat2 <- rbind(dat1, add1); dat3 <- rbind(dat2, add2); dat4 <- rbind(dat3, add3), etc. For data.frames, it functions similarly to `[<-.data.frame`, but allows you to specify the location of the rows similar to append (vs. c) and overwrite rows with the same rownames. For matrices, it offers more novel functionality since `[<-.matrix` does not exist.

Set a Vector's Names as its Elements sn sets a vector's names as its elements. It is a simple utility function equal to setNames(x, nm = as.character(x)). This is particularly useful when using lapply and you want the return object to have X as its names.
