similar to: qplot fill and colour not working as expected

I have 4 columns and 56 rows of made up data that I want to plot as a series of bar graphs. The idea is to create one bar graph for each of the 4 columns using a for loop. I tried the following command in RStudio and when I type x in the console I get just the 4th graph instead of all four graphs. I did not define what x is before hand. I was not sure what it would be. Any suggestions on how you

library(xlsReadWrite) mydata<-read.xls("file path", header=TRUE) however if I change xls to csv it works just fine. Any ideas what I'm doing wrong? I have have also using the package gdata with the exact same error. Below is the error that pops up. Error in findPerl(verbose = verbose) : perl executable not found. Use perl= argument to specify the correct path. Error in

I took some data from an online poll about which R GUI people used most and I am messing around with it to learn how to use qplot. Specifically I am making a horizontal bar graph and I have two questions. 1. The categories are ordered in rather strange way at least to me. It is not alphabetical or ascending/descending order of votes cast so i had to manually state the order I wanted which is

General problem: I have 20 projects that can be invested in and I need to decide which combinations meet a certain set of standards. The total possible combinations comes out to 2^20. However I know for a fact that the number of projects must be greater than 5 and less than 13. So far the the code below is the best I can come up with for iteratively creating a set to check against my set of

I wish to create a matrix of all possible percentages with two decimal place percision. I then want each row to sum to 100%. I started with the code below with the intent to then subset the data based on the row sum. This works great for 2 or 3 columns, but if I try 4 or more columns the number of rows become to large. I would like to find a way to break it down into some kind of for loop, so

I am just starting to experiment with writing a function and have run into what seems like a limitation or more likely a lack of understanding on my part. Very Simple Example: I want to define a function that does 1+1=2. z<-1 ADD<-function(x) { x<-x+1 } ADD(z) z output for z is 1 not the expected 2. Now if I were to do print(x+1) instead of x<-x+1 it does return 2, so the

I have several thousand rows of shipment data imported into R as a data frame, with two columns of particular interest, col 1 is the entry date, and col 2 is the tracking number (colname is REQ.NR). Tracking numbers should be unique but on occassion aren't because they get entered more than once. This creates two or more rows of with the same tracking number but different dates. I wrote a for

Hi R-helpers, I have the following (dummy) dataframe: > test DATE LOCATION KIND CLASS COUNT 1 1 1 CAR A 2 2 1 1 TRUCK D 3 3 1 1 BUS E 4 4 1 2 CAR E 2 5 1 2 TRUCK A 7 6 1 2 BUS F 1 That I would like to turn into this: > test2 DATE LOCATION KIND CLASS 1 1 1

Hi everyone. Long time listener, first-time caller here. I have a data set that's been melted with the excellent reshape package, but I can't seem to cast it the way I need to. Here's the melted data's structure: > str(mdat) 'data.frame': 6978 obs. of 4 variables: $ VehType : Factor w/ 2 levels "Car","Truck": 1 1 2 1 1 2 1 1 1 1 ... $ Year :

Can someone verify for me if the for loop below is really calculating the nonzero min for each row of a matrix? I have a bug somewhere in the is section of code. My first guess is how I am find the the nonzero min of each row of my matrix. The overall idea is to make sure I am investing all of my money, i.e. new.set is a set of indicator variables for each stock for a particular portfolio, i.e.

I''m new to rspec, so, I might be coloring outside the lines, but, there have been several instances where I have wanted to display a comment or note. for example: describe "truck" do it "should require model" do end end rspec spec --format doc truck should require model What I mean by display a comment or note would be like: truck NOTE: blah, blah,

hi I need help with list object. I have a list object > a <- c('apple','orange','grape') > b <- c('car','truck','jeep') > c <- list(a,b) > names(c) <- c('fruit','vehicle') > c $fruit [1] "apple" "orange" "grape" $vehicle [1] "car" "truck"

Dear R-helpers, I am helping a SAS user run some analyses in R that she cannot do in SAS and she is complaining about R's peculiar (to her!) way of recoding variables. In particular, she is wondering if there is an R package that allows this kind of SAS recoding: IF TYPE='TRUCK' and count=12 THEN VEHICLES=TRUCK+((CAR+BIKE)/2.2); Thanks for any help or suggestions you might be able

I'm trying to prepare some cross tabs, looking at a number of variables against a variable "connector" which has 2 values: "OD Passenger" and " Connector". When I produce a xtabs one way I have observations under "Connector" but against a different variable "Connector" shows all 0 values. What is wrong? I've looked into the na commands

I presume the behavior below (no Connector values in the second table) is because I have na values in my dataframe. How do I get them to list? I found references to na.action and na.pass, but I could not figure out how I could use them with xtabs to list the na as a value. I'm sure there's a simple syntax I need, but it's not obvious to me. > # Weighted Data

I am using if else and loop to sortout the data set that is the values less than o or more than 100 will be chosen.I could not get outTable with loop. Please help me to correct the code: I USED: # Read a_data <- read.table("D:/SNP/copy.sas", header=T, sep="\t") tr <- a_data$truck ca <- a_data$cars length <- nrow(a_data) outTable <- matrix(nrow=length,ncol=3)

Dear list, I met with a business case and feel frustrated to model it,scenario is like this 1. logistics department running 2. a lot of customers place orders and goods need to be send to their site (nationwide) 3. order received and then choose from a list of truck carriers to deliver goods,a cheapest one should be selected but might not available for the limit of order-shipment time,so a more
