Try:

R> for(i in 1:1750){tryCatch(eval(expression("sexsnp[i] = fisher.test(table(data[,3], data[,i+38]))$p")), error=function(e)print(NA))}

or

R> for(i in 1:1750){tryCatch(bquote("sexsnp[i] = fisher.test(table(data[,3], data[,i+38]))$p"), error=function(e) print(NA))}

or 

R> for(i in 1:1750){tryCatch(.("sexsnp[i] = fisher.test(table(data[,3], data[,i+38]))$p"), error=function(e) print(NA))}

If you want to use the '='.

Cheers,
