similar to: time series x axis labels

I hope this is the appropriate list for this type of question Consider the dataset below:I have a column DOC with values from 3 to 101and those are the values that I want to show on my x axis, howeverI only get 3, 3.1, 3.2 and so on. I tried to change those values with xlim(3, 101) but I getthe following error:Error in unit(x, default.units) : 'x' and 'units' must have length >

Hi: I need some help with the legend. I got 14 samples(Muestreo) and I am trying to plot a smooth line for each sample. I am able to accomplish that but the problem is that the legend only displays every other sample. How can I force the legend to show all of my Muestreos? Thanks in advance. fish_ByMuestreo <- structure(list(data = structure(list(SampleDate = structure(c(3L, 3L, 3L, 3L,

Hi all: I have been using ggplot2 graphics for quite some time now and I really like it. However, I haven't used barplots enough to understand the arquitecture behind it. Can someone show me how to make this simple barplot graph with ggplot2? I want "PondName" along the x axis and "avgWt" along the Y axis which represents the avgWt by each Pond. PondName avgWt Pond01 21.5

Dear List: I have a dataset with over 5000 records and I would like to put the Count in bins based on the ForkLength. e.g. Forklength Count 32-34 ? 35-37 ? 38-40 ? and so on... and lastly I would like to plot (scatterplot) including the SampleDate along the X axis and ForkLength along the Y axis. I recently saw an example similar to

Hi, I'm fairly new to R but I have a large dataset (300000 obs) containing patient material. Some patients came 2-9 times during the three year observation period. The patients are identified by a unique idnr, the sessions can be distinguished using the session date. How can I recode the date of the session to a session id (1-9). This would be necessary to obtain information and do some

Thanks to David's help I subset my large data set and produced a smaller one for a single stream and 7 factors of interest. The structure of this data frame is: str(burns.tds.anal) 'data.frame': 718 obs. of 4 variables: $ site : Factor w/ 143 levels "BC-0.5","BC-1",..: 1 1 4 6 4 4 4 5 5 5 $ sampdate: Date, format: "1996-06-02"
