Hello, I plotted a graph on R showing how salinity (in ?, y-axis) changes with time(in years, x-axis). However, right from the beginning on the Excel spreadsheet the v alues for salinity appeared as, for example, 35000? instead of 35?, which I gues sed must have been a typing error for the website from which I extracted the dat a (NOAA).Thus, I now would like to substitute these values with the correspondin g smaller value, as it follows: 25000 35000-> 25, 35 and so on. Is there any way I can change this on R or do I have to modify these numbers bef ore inputting the data on R (for example on Excel)? If so, can anybody tell me h ow to do either of these? Many thanks! Emanuela

Sounds like you have made no effort to learn R, e.g. by reading the Intro to R tutorial packaged with R or other online tutorial (there are many). Don't you think you need to do some homework first? -- Bert

Just calculate a new sequence if those percentages are in an orderly sequence. See ?seq v <- seq(25, 200, by = 10) or perhaps the values are actually text ?substr x <- substr(v, 1,2) John Kane Kingston ON Canada

I did look into tutorials but I could not find the exact request I am looking for. I just started using R so I am still a beginner. If you then know where I can find it, can you please redirect me to it -- View this message in context: http://r.789695.n4.nabble.com/Substituting-the-values-on-the-y-axis-tp4669165p4669171.html Sent from the R help mailing list archive at Nabble.com.
Hi Emanuela, Welcome to R It can be hard finding even relatively simple things when you are just starting. You might want to have a look at http://www.unt.edu/rss/class/Jon/R_SC/ or http://www.burns-stat.com/documents/tutorials/impatient-r/ if ou have not already seen them. Patrick Burn's site http://www.introductoryr.co.uk/R_Resources_for_Beginners.html has some useful links If you are a refugee from SAS or SPSS, this paper by Bob Muenchen is very useful www.et.bs.ehu.es/~etptupaf/pub/R/RforSAS&SPSSusers.pdf Some tricks for asking a good question in the R help list is here: https://github.com/hadley/devtools/wiki/Reproducibility or http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example In most cases it is very useful to provide some data. See ?dput in the last two links. A small bit of sample data in your original post would definately have helped. Many or most R-help readers do not use nabble and really hate to have to go there to see the context of a message. You should always leave the important parts of earlier messages to let the R-help reader see what the problems and other suggested solutions may be. John Kane Kingston ON Canada

Hi Emanuela, I think that the axis.mult function in the plotrix package will do what you want with mult=0.001. Obviously you won't want to display the transformation, so set mult.label="". Jim
