Hello all, I have a list of genes as follows (A) Number? GeneName 0???????????? YAR003W 1???????????? YAR007C 2???????????? YAR008W 3???????????? YBL035C 4???????????? YBL111C 5???????????? YBL112C And I have a list of gene interactions as follows (B) 0 -> 1 1 -> 5 3 -> 4 2 -> 3 I want to replace the values in (B) with the corresponding values in (A) ie, I want to achieve the following 0 -> 1 replaced with YAR003W ->YAR007C 1 -> 5 replaced with YAR007C -> YBL112C 3 -> 4 replaced with YBL035C ->?? YBL111C 2 -> 3 replaced with YAR008W -> YBL035C The example is simple with (A) and (B) only having a few lines.? But in reality, (A) may contain more than 1000 genes and (B) may contain thousands of interactions. Any suggestions? on how to achieve the above task are welcomed! -- Suhaila Zainudin PhD Candidate Universiti Teknologi Malaysia
How to replace values?

Hi,
If the coding would start at 1 rather than 0 then +1's in the
penultimate line could be eliminated.

gene <- c("YAR003W", "YAR007C", "YAR008W", "YBL035C", "YBL111C", "YBL112C")
print(gene)
to <- c(0,1,3,2) # to <- c(1,2,4,3)
from <- c(1,5,4,3) # from <- c(2,6,5,4)
gene[to+1] <- gene[from+1] # gene[to] <- gene[from]
print(gene)
