-
assign_expressions()
- Parse multiple R expressions into a named list of expression objects bound to symbolic names (i.e. mutated variables)
-
assign_expressions_to_afl()
- Parse multiple R expressions into a named list of AFL strings bound to symbolic names (i.e. mutated variables)
-
at_least()
- Returns TRUE if version string x is greater than or equal to than version y
-
cov(<scidb>)
- Covariance matrix This function is more limited than R's default
cov
function. It can only compute a covariance matrix from a data matrix without any missing value handling by the procedure (in R notation)S0 <- sweep(x, 2, colMeans(x))
,crossprod(S0)/(nrow(S0) - 1) # (covariance matrix result)
-
dimnames(<scidb>)
- Names of array dimensions
-
.attsplitter()
- Internal function for processing SciDB attribute schema
-
.dimsplitter()
- Internal function for processing SciDB dimension schema
-
.scidbeval()
- An important internal convenience function that returns a scidb object. If eval=TRUE, a new SciDB array is created the returned scidb object refers to that. Otherwise, the returned scidb object represents a SciDB array promise.
-
expression_parser()
- Create a scidb.expression by parsing an R expression
-
filter()
- Parse multiple R expressions into a list of boolean expressions
-
filter_to_afl()
- Parse multiple R expressions into a single AFL string
-
getpwd()
- Simple utility to interactively enter a password without showing it on the screen
-
`%as%`(<scidb>)
- AFL arrary aliasing
-
`%as%`
- AFL array aliasing
