本文介绍了如何将参数传递到函数中的函数中的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我正在写的函数涉及到来自基础R的其他函数以及很多参数。例如(真实函数更长): myfunction< - function(dataframe,Colv = NA){$ b $ (矩阵,Colv = Colv)返回(出)} 数据(矩阵,Colv = Colv) mtcars) myfunction(mtcars,Colv = NA) 许多参数可以传递给: heatmap(x,Rowv = NULL,Colv = if(symm)Rowvelse NULL, distfun = dist,hclustfun = hclust, reorderfun =函数(d,w)reorder(d,w), add.expr,symm = FALSE,revC =相同(Colv ,Rowv), scale = c(row,column,none),na.rm = TRUE, margin = 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),...) 我想使用这些参数而不在myfunction中列出它们。 myfunction(mtcars,Colv = NA,col = topo.colors(16)) myfunction中的错误(mtcars,Colv = NA,col = topo.colors(16) ): unused argument(s)(col = topo.colors(16)) 我尝试了以下但不起作用: $ b $ pre $ myfunction< - function(dataframe,Colv = NA){矩阵< - as.matrix(数据帧) out< - 热图(矩阵,Colv = Colv,....)返回(出)} 数据mtcars) myfunction(mtcars,Colv = NA,col = topo.colors(16)) 解决方案尝试使用三个点而不是四个,并将省略号参数添加到顶层函数中: (数据帧,Colv = NA,...){矩阵< - as.matrix(数据帧) out< - 热图(矩阵,Colv = Colv,...)r eturn(out)} 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 myfunction.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)) 解决方案 Try three dots instead of four, and add the ellipsis argument to the top level function:myfunction <- function (dataframe, Colv = NA, ...) { matrix <- as.matrix (dataframe) out <- heatmap(matrix, Colv = Colv, ...) return(out)} 这篇关于如何将参数传递到函数中的函数中的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
