Insert function variable into graph title

Question

I have a function with two input variables ``` min.depth<-2 max.depth<-5 ``` the function produces a plot. How can I insert the input variables into the title? I have tried: ``` plot.a<-plot(plt.a$"Traits",plt.a$"Species",xlab="Site similarity by traits (Tsim)", ylab="Site similarity by species (Jaccard)", main=c("Jaccard vs. Tsim for depths", min.depth, "to",max.depth,"m") ``` While this does insert the input variable correctly it also causes the title to stack as follows: ``` Jaccard vs. Tsim for depths 2 to 5 m ``` Any ideas on how to avoid this stacking?

Accepted Answer

You should use `paste`instead of `c`:

```
plot(..., main=paste("Jaccard vs. Tsim for depths",  min.depth, "to",max.depth,"m", sep=" "))
```

With `c` you create a vector of strings (hence the stacking), with `paste` you concatenate them into one single string.
