我有相关的函数中环的问题,我已经定义了一个函数那样:错误:找不到功能
FUN <- function(directory=dir, permutations=perm){
# Create directory
dir.create(file.path(getwd(), directory), showWarnings=FALSE)
mypath <- file.path(getwd(), directory)
require('plyr')
scores.v2 <- read.delim('scores.txt', stringsAsFactors=F)
unif.score <- function(b) {
rand.score <- runif(length(b))
new.score <- sort(rand.score/sum(rand.score), decreasing=T)
new.score
}
for (n in 1:permutations){
# Suffle gene_names in column genes
scores.v2[,2] <- sample(scores.v2[,2])
# Assign new scores according to the uniform distribution
scores.v2 <- ddply(scores.v2, "Locus", transform, Score=unif.score(Score))
# Order data.frame based on Locus and Score
scores.v2 <- scores.v2[order(scores.v2[,1],-scores.v2[,5]),]
return(scores.v2)
}
}
当我执行的功能FUN("permuted", 2)
我得到的错误Error: could not find function "unif.score"
。我可以在运行FUN
之前修复声明unif.score
的问题,但我想了解这个错误信息的行为,我认为这可能与环境,但我不知道,
非常感谢
的例子如何scores.txt
