populating matrix with binary variable after matching data from data frame

You could try:
x1$V2[1] <- "TCLA1"


? x[outer(rownames(x), colnames(x), FUN=paste) %in% as.character(interaction(x1, sep=" "))] <- 1
x
?????? TCLA1 VPS41 ABCA13 ABCA4
AKT3?????? 1???? 0????? 0???? 0
AKTIP????? 0???? 1????? 0???? 0
ABCA13???? 0???? 0????? 0???? 0
ABCA4????? 0???? 0????? 0???? 0

Hi:
sorry I have a basic question.

I have a data frame with two columns:

x1

? ? ? V1? ? ?  V2
1?  AKT3? ? TCL1A
2? AKTIP? ? VPS41
3? AKTIP? ? PDPK1
4? AKTIP?  GTF3C1
5? AKTIP? ? HOOK2
6? AKTIP? ? POLA2
7? AKTIP KIAA1377
8? AKTIP FAM160A2
9? AKTIP? ? VPS16
10 AKTIP? ? VPS18


I have a matrix 1211x1211 (using some elements in x1$V1 and some from
x1$V2). I want to populate for every match for example AKT3 = TCL1A = 1
whereas AKT3 - VPS41 gets 0)
How can i map this binary relations in x.

x

? ? ?  TCLA1 VPS41 ABCA13 ABCA4
AKT3? ? ?  0? ?  0? ? ? 0? ?  0
AKTIP? ? ? 0? ?  0? ? ? 0? ?  0
ABCA13? ?  0? ?  0? ? ? 0? ?  0
ABCA4? ? ? 0? ?  0? ? ? 0? ?  0


dput -

x = structure(c(0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0), .Dim =
c(4L,
4L), .Dimnames = list(c("AKT3", "AKTIP", "ABCA13", "ABCA4"
), c("TCLA1", "VPS41", "ABCA13", "ABCA4")))

x1 = structure(list(V1 = c("AKT3", "AKTIP", "AKTIP", "AKTIP", "AKTIP",
"AKTIP", "AKTIP", "AKTIP", "AKTIP", "AKTIP"), V2 = c("TCL1A",
"VPS41", "PDPK1", "GTF3C1", "HOOK2", "POLA2", "KIAA1377", "FAM160A2",
"VPS16", "VPS18")), .Names = c("V1", "V2"), row.names = c(NA,
10L), class = "data.frame")



Thanks
Adrian
