My issue relates to adding text to a matrix and finding that the text is
converted to a number.



This is the section of code I'm having trouble with:



# First, I load in a list of names from a .csv file to 'names'

names <- read.csv(file("Names.csv"))



# Then I define a matrix which will be populated with various test
statistics, with several rows for each entry in names



testOutput <-matrix(nrow = 200, ncol = 5)

for (i in 1:nrow(names)){



            testOutput[i,1] <- names[i,1]

            testOutput[i,2] <- names[i,2]



            # test statistics code here



}





If I look at names[,1], I get the following:



names[,1]

 [1] EQ_Level_UK       EQ_Level_EUR      EQ_Level_US       EQ_Level_Far East

 [5] IR_PC 1_UK        IR_PC 2_UK        IR_PC 3_UK        Swap_PC 1_UK

 [9] Swap_PC 2_UK      Swap_PC 3_UK      FX_Level_EUR      FX_Level_US

[13] FX_Level_Far East Infl_PC 1_UK      Infl_PC 2_UK      Infl_PC 3_UK

[17] Prop_Level_UK     CreditAAA_PC 1_UK CreditAAA_PC 2_UK CreditAAA_PC 3_UK

[21] CreditAA_PC 1_UK  CreditAA_PC 2_UK  CreditAA_PC 3_UK  CreditA_PC 1_UK

[25] CreditA_PC 2_UK   CreditA_PC 3_UK   CreditBBB_PC 1_UK CreditBBB_PC 2_UK

[29] CreditBBB_PC 3_UK

29 Levels: CreditA_PC 1_UK CreditA_PC 2_UK CreditA_PC 3_UK ... Swap_PC 3_UK



But if I look at testOutput[,1], I get:



testOutput[,1]

  [1] "15" "13" "16" "14" "23" "24" "25" "27" "28" "29" "17" "19" "18" "20"
"21"

 [16] "22" "26" "7"  "8"  "9"  "4"  "5"  "6"  "1"  "2"  "3"  "10" "11" "12"
"17"

 [31] NA   NA   "19" "18" NA   NA   NA   "20" NA   NA   "21" NA   NA   "22"
NA

 [46] NA   "26" NA   NA   "7"  NA   NA   "8"  NA   NA   "9"  NA   NA   "4"
NA

 [61] NA   "5"  NA   NA   "6"  NA   NA   "1"  NA   NA   "2"  NA   NA   "3"
NA

 [76] NA   "10" NA   NA   "11" NA   NA   "12" NA   NA   NA   NA   NA   NA
NA

 [91] NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA
NA

[106] NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA
NA

[121] NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA
NA

[136] NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA
NA

[151] NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA
NA

[166] NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA
NA

[181] NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA   NA
NA

[196] NA   NA   NA   NA   NA



That is, the names are now converted to numbers. I think this might have
something to do with the way I've defined the testOutput matrix, but haven't
been able to find any information about how to fix it. Can anyone help?



Many thanks.
