how to pass arguments into function within a function in r
- by jon
I am writing function that involve other function from base R with alot of arguments. For example (real function is much longer):
myfunction <- function (dataframe, Colv = NA) {
matrix <- as.matrix (dataframe)
out <- heatmap(matrix, Colv = Colv)
return(out)
}
data(mtcars)
myfunction (mtcars, Colv = NA)
The heatmap has many arguments that can be passed to:
heatmap(x, Rowv=NULL, Colv=if(symm)"Rowv" else NULL,
distfun = dist, hclustfun = hclust,
reorderfun = function(d,w) reorder(d,w),
add.expr, symm = FALSE, revC = identical(Colv, "Rowv"),
scale=c("row", "column", "none"), na.rm = TRUE,
margins = c(5, 5), ColSideColors, RowSideColors,
cexRow = 0.2 + 1/log10(nr), cexCol = 0.2 + 1/log10(nc),
labRow = NULL, labCol = NULL, main = NULL,
xlab = NULL, ylab = NULL,
keep.dendro = FALSE, verbose = getOption("verbose"), ...)
I want to use these arguments without listing them inside myfun.
myfunction (mtcars, Colv = NA, col = topo.colors(16))
Error in myfunction(mtcars, Colv = NA, col = topo.colors(16)) :
unused argument(s) (col = topo.colors(16))
I tried the following but do not work:
myfunction <- function (dataframe, Colv = NA) {
matrix <- as.matrix (dataframe)
out <- heatmap(matrix, Colv = Colv, ....)
return(out)
}
data(mtcars)
myfunction (mtcars, Colv = NA, col = topo.colors(16))
