I have two vectors min 0.2, 0.3, 0.6, 0.1 max 0.4,0.5,0.7,0.4 Is there a way to combine these two vector so that the values will be taken from the vectors alternating so that I will get a new minmaxminmaxminmax-vector? minmax 0.2,0.4,0.3,0.5,0.6,0.7,0.1,0.4 Any help is much appreciated -- View this message in context:

I was just thinking of a way to present data and if it is possible in R. I have a data frame that looks as follows (this is just mockup data). df location,"species1","species2","species3","species4","species5" "loc1",0.44,0.28,0.37,-0.24,0.41 "loc2",0.54,0.62,0.34,0.52,0.71 "loc3",-0.33,0.75,-0.34,0.48,0.61 location

I have a file that reads like this: Species,Year,Julian_day Alnus_glutinosa, 1873, 123 Sorbus_aucuparia, 1873, 122 ....(more species...) Alnus_glutinosa, 1874, 134 Sorbus_aucuparia, 1874, 143 ....(more species and years) Is there a way to plot this as julian day over years so that each species get a different color? Also is it possible to convert this data into the format: Alnus_glutinosa,

If I have a data frame where a species occupies several rows with different phases such as (both col's ar factors): species,phase Populus tremula,1 Populus tremula,2 Populus tremula,3 Calluna vulgaris,1 Calluna vulgaris,2 Betula alba,1 Betula alba,2 Betula alba,3 Primula veris,1 Primula veris,2 and another df where each species only have one row: species,growth_form Populus tremula,tree Acer

I am trying to set u a limit for my plot window according to the range of a year column I have. The first year in the range is just simply the first row, referred to as data$year[1]. How can I find the last row in a similar way to set the last year in the range? What I want to accomplish is the following: "plot(....,xlim = c(data$year[1], data$data[lastrow]),...)", is this possible? --

I was just wondering if anyone knows what could be the problem with my exporting of plots. Below is the error messages I get when trying to export my plots (all error messages at the same time). I do get a file produced which works but I don't know why these messages appear. Doesn't matter if it is a pdf or a png or any other format I export to. Also, when exporting to png I get
