*I have the following function:*
/plot_mi_time = function(mdata, miname) {
mdata2 = mdata[row.names(hakat) == miname, ]
print(mdata2)
xcoords <- c(1,1,2,2,3,3,4,4,5,5,6,6)
plot(c(xcoords), mdata2, xaxt="n", ylab="Expression",
xlab="Time(h)", ,
main=miname)
axis(1, at=xcoords,
labels=c("a","a","b","b","c","c","d","d","e","e","f","f"))
}/
*The function is supposed plot a row from the following input-table:*
/ X1h X4h X9h X15h X18h X21h
hsa-miR-99b* 173 64 66 56 65 65

*When running the function I get the following errro messag*e:

Error in `[.data.frame`(mdata, row.names(hakat) == miname, ) :

*Anyone know how to use the function correct?*

I believe it's a problem in your variable name "hsa-miR-98". R wants to interpret that as "hsa" less "miR" less 98. Since you don't have a variable called "hsa", R (rightly) complains. Call ls() and see what R thinks your variables are named -- that will hopefully make the problem evident. Hope this helps, Michael Weylandt PS -- in your plot() call, you don't need a "c" around xcoords.

The simplest fix is to pass "hsa-miR-98" instead. A more complicated alternative is to use deparse(substitute(miname)) in place of miname in the function: that converts the expression to a string.
