Plotting a single row with NA values in R

I have a table flipped whose first row I would like to visualize with the plot() funciton in R. How is it possible to do this with a simple command given that NA values must not be present in the arguments of plot() ? 

> flipped[1,]
  variable 26500 30000 30100 30700 31600 33700 33800 33900 34000 34600 34800 35100 35200 35300 35400 35600 35800
1      -20    NA     0    NA    NA    10    20    NA    NA    NA    30    NA    NA    NA    NA    40    NA    NA
  35900 36200 36300 36400 36700 36900 37000 37200 37800 37900 38000 38200 38800 39000 39100 39200 39700 39800 39900
1    NA    50    NA    NA    NA    NA    NA    60    NA    NA    NA    70    NA    NA    NA    80    NA    NA    NA
  40000 40200 40600 40700 40800 41700 41800
1    NA    90    NA    NA    NA   100    NA

na.omit() removes the entire row, and is not a parameter in the plot() funciton. As for the y axis, I understand that the colnames must be made numeric fist before being plotted :

as.numeric(colnames(flipped[2:ncol(flipped)]))
 [1] 26500 30000 30100 30700 31600 33700 33800 33900 34000 34600 34800 35100 35200 35300 35400 35600 35800 35900 36200
[20] 36300 36400 36700 36900 37000 37200 37800 37900 38000 38200 38800 39000 39100 39200 39700 39800 39900 40000 40200
[39] 40600 40700 40800 41700 41800

How would one go about plotting x(1st row with NAs removed) over y(corresponding colnames) in this case?

We can use is.na on the unlisted row 

v1 <- unlist(flipped[1, -1])
plot(v1[!is.na(v1)], names(v1)[!is.na(v1)])
