我正在尝试运行此脚本:
input <- read.csv ("trio.csv")
for (i in 1:nrow(input)) {
if (input[i, 6] == input[i, 2]) {
if (input[i, 7] == input[i, 4] |
input[i, 7] == input[i, 7]) {
print ("h1")
} else {
print ("not h1")
}
} else if (input[i, 6] == input[i, 3]) {
if (input[i, 7] == input[i, 4] | input[i, 7] == input[i, 7]) {
print ("h1")
} else {
print ("not h1")
}
} else {
print("not h1")
}
}
for (j in 1:nrow(input)) {
if (input[j, 7] == input[j, 2]) {
if (input[j, 6] == input[j, 4] | input[j, 6] == input[j, 7]) {
print ("h2")
} else {
print ("not h2")
}
} else if (input[j, 7] == input[j, 3]) {
if (input[j, 6] == input[j, 4] |input[j, 6] == input[j, 7]) {
print ("h2")
} else {
print ("not h2")
}
} else {
print("not h2")
}
}
trio.csv文件由7列和100行组成,下面是trio.csv的示例:
dput(head(input))
structure(list(familyID = c(1001L, 1004L), Pat1 = structure(2:1, .Label =
c("REF", "X1"), class = "factor"), Pat2 = structure(1:2, .Label = c("C2",
"REF"), class = "factor"), Mat1 = structure(1:2, .Label = c("C2",
"REF"), class = "factor"), Mat2 = structure(c(1L, 1L), .Label = "C2",
class = "factor"),
Ch1 = structure(2:1, .Label = c("REF", "X1"), class = "factor"),
Ch2 = structure(1:2, .Label = c("C2", "REF"), class = "factor")),
row.names = 1:2, class = "data.frame")
如何将第一个循环和第二个循环的结果保存在新文件的两个不同列中?
答案 0 :(得分:0)
这是我设法将两个循环的结果保存到两个新的csv文件中的方法,它对我有用。欢迎提出所有提高效率的建议。谢谢
