lapply(X, FUN, …) X表示一个向量或者表达式对象,其余对象将被通过as.list强制转换为list 例: > x <- list(a = 1:10, beta = exp(-3:3), logic = c(TRUE,FALSE,FALSE,TRUE)) > x $a [1] 1 2 3 4 5 6 7 8 9 10 $beta [1] 0.04978707 0.13533528 0.36787944 1.00000000 2.71828183 7.38...
# ellipses as an argument in a function. Below I have an example function that # is supposed to add two explicitly named arguments called alpha and beta. # # add_alpha_and_beta <- function(...){ # # First we must capture theellipsisinside of a list # # and then assign the list ...

Logical values and text representations of numbers that you type directly into the list of arguments are counted. If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included. ...
N element character vector containing the names of the dependent variables in the specified model. partitions when cube isTRUE, partitioned results will also be returned. fstatistics (for models including non-intercept terms) a list containing the named elements:value:an N element numeric vector of...
importONNXFunction supports the following ONNX operators for conversion into built-in MATLAB layers or custom layers, with some limitations. For a list of equivalent built-in or custom layers obtained using importNetworkFromONNX, see ONNX Operators Supported for Conversion into Built-In MATLAB Laye...
The following are possible cases where fork may be called. Obviously, this is not an all-inclusive list: *nohupto launch jobs. This will cause a fork to be called. * Usingmulticoreand/ordoMCto launch R processes with RevoScaleR Note that when usingrxExec, the default behavior for any wor...
When this function is enabled, locked IP addresses fail to pass authentication and are displayed in the display ssh server ip-block list command output. If this function is disabled, the display ssh server ip-block list command does not display any previously locked IP addresses or IP addresses...
