【问题描述】：
我有一个简单的函数，它应该逐行读取文本文件并生成浮点值矩阵。函数在这里：
testCNVs <- function(infile){
dataLines <- readLines(infile) # read the input file into a character vector
nLines <- length(dataLines)
splitLines <- strsplit(dataLines," ") # create a list with nLines elements
print(length(splitLines))
convLines <- sapply(splitLines,function(x) {as.numeric(x)}) # convert the list to numbers with NAs for the blanks
print(length(convLines))
numLines <- sapply(convLines,function(x){x <- na.omit(x)}) # change the NAs to blanks
print(dim(numLines))
}
打印语句用于监控进度。我有两个非常相似的数据文件（显然只在原始文件中的行数不同）。我的问题是该功能失败了一个而不是另一个。问题似乎是我将文本行拆分为数字时创建的列表元素转换的行。在一种情况下，我最终得到了所需的 18x124 矩阵，在另一种情况下，我最终得到了 1x896 向量。为什么会发生这种情况？这是两个数据文件。
