下面给出的一段 R 代码旨在对一个文件夹中的许多文件 (12) 执行计算。但我收到此错误:
错误:下标超出范围。
它完成了第一个文件的读取,但是当它开始读取下一个文件时出现了错误。任何建议为什么?
library(Matrix)
setwd("C:\\Users\\Desktop\\img")
listfile <- dir()
long <- file("C:\\Users\\Desktop\\New folder (5)\\vfd.bin", "rb")
A = readBin(long, integer(), size=2,n=67420*1, signed=F)
ta <- t(A)
lot <- file("C:\\Users\\Desktop\\New folder (5)\\lat.img", "rb")
B = readBin(lot, integer(), size=2,n=67420*1, signed=F)
tb <-t (B)
for (n in 1:length(listfile))
{
h = listfile[n]
b = file.info(h[n])$size/67420/4
wind <- file(h, "rb")
C = readBin(wind, double(), size=4,n=67420*b, signed=TRUE)
D <- matrix(C,nrow=b,ncol=67420)
for(d in 1:b)
{
M <- Matrix(-9999, 360, 720)
tm <- t(M)
for(i in 1:67420)
{
tm[ta[i],tb[i]] = round(10 * ((D[(d-1)*8+1,i] + D[(d-1)*8+2,i] + D[(d-1)*8+3,i] + D[(d-1)*8+4,i] + D[(d-1)*8+5,i] + D[(d-1)*8+6,i] + D[(d-1)*8+7,i] + D[(d-1)*8+8,i] ) / 8))
} ###gooooooood
to.write <- sprintf("C:\\Users\\Desktop\\New folder (6)\\Yar_%00d.bin", d)
writeBin(as.integer(tm@x), size=2,to.write)
}
}
