[R] Periods instead of spaces in dataframe names?

when I use names() to extract the name of a dataframe element, why does it
have "." instead of " " between words?
I'm importing a CSV file of survey results for analysis. I read them like
df <- read.csv("surveydata.csv",nrows=40,header=TRUE,
To do a summary of the responses to a question, I can now do something like
1 2 3 4
13 13 4 2
and can then do a barplot with:
Which is fine. But since the first row of my data file includes the questions
themselves, I want to use those questions as chart titles, like this:
This gives an unexpected result: the title has a "." where every space should
be between words, like this: "How.many.cats.do.you.own"
I can't figure out why, or how to get spaces instead of "." to show up. I've
tried using gsub but without success, to substitute " " for "."
I'm think I'm confused about something fundamental here, and hope someone has
the patience to enlighten me. I confess to a being a bit vague in my
understanding of R's handling of arrays, dataframes, and vectors. My
background is in C programming and I keep looking for a "string"...
Thank you very much. Please reply or copy me directly if you respond.
