Formatting of numbers on y axis
Hello all. I have the following: plot(salaries$yearID, salaries$salary, type='n', xaxt='n', xlab='', yaxt='n', ylab='') axis(1, at=unique(salaries$yearID), labels=unique(salaries$yearID), lwd=.25, tck=-0.05) axis(2, axTicks(2), format(axTicks(2), scientific = F)) Which nicely creates the Y axis with the raw numbers, which are in the range of .5 - 7

Stacked bar chart help.
Can't figure this out. I have the following list of salary averages per year, per position. The dput output is: > dput(salaries) structure(list(yearID = c(2009, 2009, 2009, 2009, 2009, 2009, 2009, 2009, 2009, 2008, 2008, 2008, 2008, 2008, 2008, 2008, 2008, 2008), AVG = c(8956855.61, 7886684.166126, 7534048.43102, 7406439.339471, 7219148.437934, 6697734.908336, 6400379.88398,

Lahman Baseball Data Using R DBI Package
Hi Philip, You've probably realized by now that R doesn't like column names that start with a number. If you try to access an R-dataframe column named 2B or 3B with the familiar "$" notation, you'll get an error: > library(DBI) > library(RSQLite) > con2 <- dbConnect(SQLite(), "~/R_Dir/lahmansbaseballdb.sqlite") > Hack12Batting <-

Lahman Baseball Data Using R DBI Package
This is really a feature of SQL, not R. SQL requires that you double quote column names that start with numbers, include spaces, etc., or that are SQL key words. E.g., > d <- data.frame(Order=c("sit","stay","heel"), Where=c("here","there","there"), From=c("me","me","you")) >

Lahman Baseball Data Using R DBI Package
I?m trying to pull data from one table (batting) in the Lahman Baseball database. Notice X2B for doubles and X3B for triples ? fourth and fifth from the right. The dbGetQuery function runs fine when I leave there two out but I get error messages (in red) when I include 2B/3B or X2B/X3B. Can anyone give me some direction? Thanks, Philip Heinrich

The double quotes are required by SQL if a name is not of the form letter-followed-by-any-number-of-letters-or-numbers or if the name is a SQL keyword like 'where' or 'select'. If you are doing this from a function, you may as well quote all the names. -Bill On Fri, Oct 2, 2020 at 6:18 PM Philip <herd_dog at cox.net> wrote: > The \?2B\? worked. Have no idea why. Can

Beginner Q- dates in the xrange?
Hi all- terribly beginner question here, but I can't figure out how to put dates as the values for my x range in a plot. Example: xrange <- results$current yrange <- results$DIFF plot(xrange, yrange, type="n", xlab="Date", ylab="Differential") lines(results$DIFF, type="l", lwd=1.5, col="red") Where xrange is: > xrange [1]

Formatting the length one vector to match another?
I have xrange which is a range of values from 1 to a max of 162. I have a yrange of values which really could be any values, but there's a min and a max. I'd like to create N number of steps between the min and the max so the length matches the xrange, so that I can plot them together. Any tips? Thank you! -- Wells Oliver wells@submute.net [[alternative HTML version deleted]]

Working with lists with numerical names
Greetings! I'm have a hard time working with some data I imported from a baseball database. Several of the database columns have numbers in them (2B, 3B), and when I try to use these vectors from the data frame, I get syntax errors, probably because it's interpreting the name as a number: > show(batting2005) playerID yearID stint teamID lgID G AB R H 2B 3B HR RBI SB CS BB

Single plot multiple levels in x?
Plotting with 2 x axis? One axis inside another, for example salary within state, 1-50 | 50 ? 100 | 100+ | 1- 50 | 50 -100 | 100+ | ? repeated bins for salary AL ! AR ?? more states The values are all stored with a single data frame. I have tried different things with the axis function and done many

problem post request with RCurl
Hi, I am trying to use a CGI service (Pubchem PUG) via RCurl and am running into a problem where the data must be supplied via POST - but I don't know the keyword for the argument. The data to be sent is an XML fragment. I can do this via the command line using curl: I save the XML string to a file called query.xml and then do curl -d @query.xml

Create new data frame with conditional sums
Under the hood, sapply() is also a loop (at the interpreted level).

read big text file into R
Dear Rs: Hi, I am trying to read a big text file (nrows=243440, ncols=144). It seems the computational time of all the read methods (scan,readtable,read.delim) is not linear to the number of rows I want to read in: things became really slow once I tried to read in 100000 lines compare to 10000 lines). If I am reading the profiling result right, I guess scan wouldn't help either. My

profiler and loops
Hello, (This is follow up from this thread: http://www.nabble.com/execution-time-of-.packages-td22304833.html but with a different focus) I am often confused by the result of the profiler, when a loop is involved. Consider these two scripts: script1: Rprof( ) x <- numeric( ) for( i in 1:10000){ x <- c( x, rnorm(10) ) } Rprof( NULL ) print( summaryRprof( ) ) script2:

Create new data frame with conditional sums
Well, here's one way to do it: (dat is your example data frame) Cutoff <- seq(0, .15, .01) Pop <- with(dat, sapply(Cutoff, \(p)sum(Totpop[Pct >= p]))) I think there must be a more efficient way to do it with cumsum(), though.
