[R] superscript in figures - basic question

2005-06-13 Thread Benjamin M. Osborne
Although I see similar, but more complex, questions addressed in the help archive, I'm having trouble adding superscripted text to the y-axis labels of some figures, and I can't find anything in the R documentation on this. I have: ylab=BA (m2/ha) but I want the 2 to be superscripted. Thanks in

[R] R-squared in summary(lm...)

What is the difference between the two R-squareds returned for a linear regression by summary(lm...)? When might one report multiple vs. adjusted R-squared? Thank you, Ben Osborne -- Botany Department University of Vermont 109 Carrigan Drive Burlington, VT 05405 [EMAIL PROTECTED] phone:

[R] calling objects in a foreloop

2005-03-14 Thread Benjamin M. Osborne
I want to organize outputs from several regressions into a handy table. When I try the following, each of my fit_s is replaces instead of read. Is there a way to read from the regression summaries that does not require writing separate lines of code for each? -Ben Osborne

[R] scaling axes when plotting multiple data sets

2005-02-16 Thread Benjamin M. Osborne
1) When adding additional data sets to a plot using plot followed by lines, is there a way to automate the scaling of the axes to allow for all data sets to fit within the plot area? 2) I attempted to solve this by setting xlim=c(min(c(data1,data2,data3)),max(c(data1,data2,data3))) however,

[R] coercing a list to a data frame, lists in foreloops

2005-01-31 Thread Benjamin M. Osborne
I have a set of time-series climate data with missing entries. I need to add rows for these missing entries to this data set. The only way I know to do this is unsing a foreloop, but this won't work on a list. I've tried to convert the list to a data frame, but that won't happen, either. I

[R] chron: parsing dates into a data frame using a forloop

2005-01-25 Thread Benjamin M. Osborne
I have one data frame with a column of dates and I want to fill another data frame with one column of dates, one of years, one of months, one of a unique combination of year and month, and one of days, but R seems to have some problems with this. My initial data frame looks like this (ignore the

[R] AIC, glm, lognormal distribution

2004-12-12 Thread Benjamin M. Osborne
I'm attempting to do model selection with AIC, using a glm and a lognormal distribution, but: fit1-glm(BA~Year,data=pdat.sp1.65.04, family=gaussian(link=log)) ## gives the same result as either of the following: fit1-glm(BA~Year,data=pdat.sp1.65.04, family=gaussian)

[R] variable object naming

2004-11-21 Thread Benjamin M. Osborne
Is it possible to give a temporary object a name that varies with each run of a foreloop? For example, I want to fill a matrix every time I run a loop, and I want a new matrix with each run, with an appropriate new name. i.e.: for(i in 1:5){... matrix.i-some values ...} so that in the end I

[R] functions

2004-10-09 Thread Benjamin M. Osborne
Does anyone know of a list of functions that R already knows? I can't seem to find this anywhere in the help documentation. For example, I want to count the number of occurences of a certain value in a column of a data frame: What do I have to do to tell R to Count? Thanks, Ben Osborne --
