bdFrame
Object
bdFrame
object, from a combination of
bdFrame
,
bdVector
,
data.frame
, and vector inputs.
This function requires the bigdata library section to be loaded.
bdFrame(..., check.names=T, na.strings="NA", stringsAsFactors=F)
bdVector
and other
bdFrame
objects.
Matrices, lists, data frames and bdFrames
provide as many variables to the new data frame
as they have columns, elements, or variables, respectively.
The treatment of objects appearing in a call depends on the existence of corresponding methods for .
TRUE
,
the variable names will be made into legal S object names,
by replacing illegal characters, like blanks, parentheses, or commas
by
.
(type
?make.name
for details).
na.strings
are considered to be missing values.
The default is "NA".
character(0) means that no strings will be considered missing values.
TRUE
then convert character arguments to
factors whose levels are the unique strings in the argument.
This may save time and space if there a many repeated values in
the strings and may make the statistical modelling functions
easier to use.
bdFrame
consisting of all the variables supplied
in the arguments.
The variables are required to have the same number of observations.
A
bdFrame
is similar to a
data.frame
,
and this function is like
in how it handles inputs that are not
bdFrame
or
bdVector
objects.
A
bdFrame
object can contain columns of only types
double
,
character
,
factor
,
timeDate
,
timeSpan
or
logical
.
