lsos: R Object List

In AngusWright/LAMBDAR: Measure galaxy fluxes from an arbitrary FITS image using input aperture locations and dimensions

R Object List

Description

A better object list

Usage

lsos(pattern="", envir=NULL, pos = 1, order.by="Size",
decreasing=TRUE, head=TRUE, n=10,noShow="",exact=FALSE)

Arguments

pattern	character; the pattern to search for in the object list
envir	environment; the environment to list
pos	integer; environment position
order.by	character; field name to order object list by. Options are "Type", "Size", "PrettySize", "Rows", "Columns", "Value".
decreasing	logical; if TRUE, objects are listed in decreasing order
head	logical; if TRUE, only the first ‘n’ objects are listed
n	integer; number of items to list when ‘head’ is specified
noShow	character vector; fields to not show. Can be any combination of "type", "size", "pretty", "dim", "vals".
exact	logical; only show items that match 'pattern' exactly.

Details

A simple procedure to list objects matching ‘pattern’ in enviroment at ‘pos’, including details on objects type, size, and dimensions.

Value

data frame;

Type	Object class/type
Size	Size of the object (bits)
PrettySize	Size of the object in nearest major unit
Rows	Number of rows in the object
Columns	Number of columns in the object

Examples

#Load LAMBDAR
library(LAMBDAR)

#Add some things to the an environment
param.env<-new.env(parent=environment())
assign("x",runif(1),envir=param.env)
assign("y",runif(1E5),envir=param.env)
assign("z",runif(1E2),envir=param.env)
assign("string","Methinks it is like a weasel",envir=param.env)
assign("im",matrix(runif(1E6),1000,1000),envir=param.env)
assign("bigmat",matrix(runif(1E8),10000,10000),envir=param.env)

#Show the parameter space variables
lsos(envir=param.env)

#Only show the type and pretty size
lsos(envir=param.env, noShow=c("size","dim","vals"))
