Hi all,
I'm not getting the right results for values that are >99 using the if
else function. The following illustrates the problem
> x <- as.matrix(read.table("test.txt"))
> x
V1 V2 V3
[1,] 47 1 43
[2,] 83 2 42
[3,] 1 3 41
[4,] 39 4 40
[5,] 23 5 39
[6,] 23 6 38
[7,] 39 7 37
[8,] 32 8 36
[9,] 73 9 35
[10,] 124 10 34
Specifying the followng condition,
if ( x <20){
y <- x +100
} else {
y <- x -100
}
> y
V1 V2 V3
[1,] -53 -99 -57
[2,] -17 -98 -58
[3,] -99 -97 -59
[4,] -61 -96 -60
[5,] -77 -95 -61
[6,] -77 -94 -62
[7,] -61 -93 -63
[8,] -68 -92 -64
[9,] -27 -91 -65
[10,] 24 -90 -66
The output generated contains 'errors.
For example, given that x < 20,
for x = 1, the output should be x+100 = 1 + 100 = 101.
However, the generated output is -99.
In addition, there is the following warning message which I don't know
what it means
the condition has length > 1 and only the first element will be used
The problem is solved if I use the ifelse function but I want to specify
the code as following;
if (/condition/) {
/statement 1a
statement 1b
/} else {
/statement 2a
statement 2b
/}
Thanks.
Muhammad
