http://r.789695.n4.nabble.com/file/n3555898/example.jpg Hi, I have a CSV-file (see image) that I would like to plot. I want to make a plot-function where I only plot one row at the time. I want to define which row to plot in the function based on the row-names (non-numeric) in column 1 in the CSV-file. Could you help me out? -- View this message in context: http://r.789695.n4.nabble.com/Plot-rows-of-CSV-tp3555898p3555898.html Sent from the R help mailing list archive at Nabble.com.
Hi,
This is not fancy or especially elegant, but....
## so you can see each plot at a time before moving on
par(ask = TRUE)
## apply() the function plot() to each row of the
## rows of mtcars you extracted by name
apply(mtcars[c("Mazda RX4", "Merc 450SLC", "Maserati
Bora"), ], 1, plot)
I use as an example the mtcars dataset. As long as you have your data
in R with row names, something like this should work. Importantly,
apply() coerces the object it functions on to a matrix, so if you have
character and numeric data, everything will be converted to the
highest level of the hierarchy (see the documentation for ?cbind to
see the hierarchy of data types).
If you need more specific types of plots, be more specific ;)
Cheers,
Josh

http://r.789695.n4.nabble.com/file/n3558595/help_snap.jpg Why do R rename my rows and columns when loading it like in the image above? -- View this message in context: http://r.789695.n4.nabble.com/Plot-rows-of-CSV-tp3555898p3558595.html Sent from the R help mailing list archive at Nabble.com.
Because your header contains strings that are not legal names. Check out the parameter check.name (cannot tell for sure since R is not available on the iPad).

Hi,
this works: apply(mtcars[c("Mazda RX4", "Merc 450SLC",
"Maserati Bora"), ],
1, plot)
How do you add labels and additional edit in such a plot? For instance I
want
mpg cyl disp hp drat wt qsec vs am gear carb to be plottet below the
X-axis
