Hi R user

I need to read in some values from a computer program output.

I can't change the output format because the developer of the program doesn't allow to change the format of output.

There are two formats.

First one looks like this

if I have 10 variables,

[ 1] [2] [3] [4] [5]

[ 1] 0.000 [ 2] 0.001 0.000 [ 3] -0.002 0.019 0.000 [ 4] 0.012 -0.004 -0.020 0.000 [ 5] -0.015 0.003 0.011 0.008 0.000 [ 6] 0.005 -0.008 -0.005 0.002 0.005 [ 7] 0.008 -0.007 0.013 0.003 0.007 [ 8] -0.014 -0.011 -0.010 -0.025 0.002 [ 9] 0.006 0.003 -0.010 0.002 -0.020 [10] 0.006 0.010 -0.006 0.005 0.008 [ 6] 0.000 [ 7] -0.037 0.000 [ 8] 0.010 0.027 0.000 [ 9] 0.032 -0.004 0.008 0.000 [10] -0.008 -0.011 0.015 -0.020 0.000 ------------------------------------------------------------------------------------------------NOTE: I put [number] to show that this output is similar to a lower diagonal matrix including diagonal. In an ouput there is no [number]

The second format looks like this

[1] [2] [3] [4] [5]

[ 2] -0.002 [ 3] 0.003 -0.053 [ 4] -0.026 0.010 0.045 [ 5] 0.023 -0.008 -0.025 -0.016 [ 6] -0.012 0.023 0.013 -0.005 -0.011 [ 7] -0.031 0.031 -0.054 -0.013 -0.027 [ 8] 0.040 0.042 0.031 0.075 -0.007 [ 9] -0.012 -0.009 0.023 -0.005 0.037 [10] -0.013 -0.027 0.014 -0.013 -0.020 [ 7] 0.127 [ 8] -0.035 -0.166 [ 9] -0.083 0.015 -0.027 [10] 0.021 0.047 -0.052 0.048 ---------------------------------------------------------------------------------------------------------NOTE: I put [number] to show that this output is similar to a lower diagonal matrix without diagonal. In an ouput there is no [number]

The problem of this format is the fixed column length ( 5 columns)

To make matter worse, the number of variables keep changing (10, 20, 30, 40, 50, 60,70,80,90, and 100) so I need to take into the number of variables when I write a R function to read in these numbers.

If the number of variables is 80, the output is very long.

I only came up with this tedious one.

First I read in the output using scan() and then make it a numeric vector

I created 10 character vectors. Creating a 100 variable character vector is the most boring things

I have ever done.

one of the character vectors that matchs with the first 10 variable output is

first.10<-c(

* "i.001.001",
** "i.002.001","i.002.002",
** "i.003.001","i.003.002","i.003.003",
** "i.004.001","i.004.002","i.004.003","i.004.004",
*

"i.005.001","i.005.002","i.005.003","i.005.004","i.005.005",

* "i.006.001","i.006.002","i.006.003","i.006.004","i.006.005",
** "i.007.001","i.007.002","i.007.003","i.007.004","i.007.005",
** "i.008.001","i.008.002","i.008.003","i.008.004","i.008.005",
** "i.009.001","i.009.002","i.009.003","i.009.004","i.009.005",
** "i.010.001","i.010.002","i.010.003","i.010.004","i.010.005",
** "i.006.006",
** "i.007.006","i.007.007",
** "i.008.006","i.008.007","i.008.008",
** "i.009.006","i.009.007","i.009.008","i.009.009",
** "i.010.006","i.010.007","i.010.008","i.010.009","i.010.010"
*

)

one of the character vectors that matchs with the second 10 variable output is

second.10<-c(

"i.002.001",

* "i.003.001","i.003.002",
** "i.004.001","i.004.002","i.004.003",
** "i.005.001","i.005.002","i.005.003","i.005.004",
** "i.006.001","i.006.002","i.006.003","i.006.004","i.006.005",
** "i.007.001","i.007.002","i.007.003","i.007.004","i.007.005",
** "i.008.001","i.008.002","i.008.003","i.008.004","i.008.005",
** "i.009.001","i.009.002","i.009.003","i.009.004","i.009.005",
** "i.010.001","i.010.002","i.010.003","i.010.004","i.010.005",
** "i.007.006",
** "i.008.006","i.008.007",
** "i.009.006","i.009.007","i.009.008",
** "i.010.006","i.010.007","i.010.008","i.010.009"
*

)

and then assign the character vector to the numeric vector by

names<-first.10

first.10 = numeric.vector

combined.one <- cbind(names,first.10)

container <- diag(10)

for (i in 1:(10*10))

{

k <- as.numeric(substr(combined.one[i,1],7,9)) l <- as.numeric(substr(combined.one [i,1],3,5)) val <- as.numeric(combined.one [i,2]) container [k,l] <- val

}

container <- t(container )

Is there any other neat way to do this?

Any help would be appreciated
