[R] Simple plotting errors

Dear R Users,

I have 12 data frames, each of 12 rows and 2 columns.

e.g. FeketeJAN
                   MEAN    SUM_
AMAZON      144.4997874 68348.4
NILE          5.4701955  1394.9
CONGO        71.3670036 21196.0
MISSISSIPPI  18.9273250  6511.0
AMUR          1.8426874   466.2
PARANA       58.3835497 13486.6
YENISEI       1.4668313   592.6
OB            1.4239179   559.6
LENA          0.9342164   387.7
NIGER         4.7245709   826.8
ZAMBEZI      76.6893794  8665.9
YANGTZE      10.6759257  1729.5


I want to do a line plot of the value of Amazon 'Sum' (in this case,
68348.4) for each of the 12 data frames. I've tried doing this as follows:

plot(FeketeJAN[1,2], FeketeFEB[1,2], FeketeMAR[1,2], *through to December*
type="l")

but receive: Error in strsplit(log, NULL) : non-character argument


I've also tried:

plot(FeketeJAN$AMAZON[,2], FeketeFEB$AMAZON[,2], *through to December*
type="l")

but receive:

Error in plot.window(...) : need finite 'xlim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf
3: In min(x) : no non-missing arguments to min; returning Inf
4: In max(x) : no non-missing arguments to max; returning -Inf


What is it that I'm doing wrong?!

Many thanks for any advice,

Steve

Well, beside the infelicity of having 12 data.frames to represent one 
year, your need to make a vector of those values as in:


plot(c(FeketeJAN[1,2], FeketeFEB[1,2], FeketeMAR[1,2], *through to 
December* ), type="l")

[R] Simple plotting errors

I'd suggest you first combine the 12 data.frames into one, using  
melt() from the reshape package.

makeDummy <- function(.){ # since you don't provide a reproducible  
example
	
	data.frame(x=letters[1:10], y=rnorm(10))
}


listOf12DataFrames <- lapply(1:12, makeDummy)

library(reshape)
dm <- melt(listOf12DataFrames, id="x")
str(dm) # each original data.frame is identified by the integer L1

with(subset(dm, x=="a"),
plot(L1, value, t="l"))

[R] Simple plotting errors

you mean you want to plot "SUM" against month? (assuming these12 data
frames
are 12 months).

you could first bind them all together using data.frame(), see ?data.frame 
which would make it much easier.

you need to create a variable for months then plot it against your variable. 
If you dont want to make it easier with a data frame then you would have a 
long piece of code as follows (assuming I have understood you correctly)

plot(seq(1:12),c(FeketeJAN$(SUM_)[row.names(FeketeJAN)=="AMAZON"],FeketeFEB$(SUM_)[row.names(FeketeFEB)=="AMAZON"]....etc))

Cheers, Si.

[R] Simple plotting errors

One way is to create a list of the dataframes and then use 'sapply' to
extract the values:

df.list <- list(FeketeJAN, ..., FeketeDEC)
plot(sapply(df.list, function(a) a["AMAZON", "SUM_"]))

try plot( c(FeketeJAN[1,2], FeketeFEB[1,2], ...)),type="l")

however it is better to create one big data frame like:

Location Mean Sum Month
Amazon   144  ... JAN

all you need is cbind.

[R] Simple plotting errors

Here is a slight elaboration on Jim's solution:

# create a vector of the names - month.abb is built into R
# This is like:  df.names <- c("FetekeJAN", "FetekeFEB",
...)
# but avoids having to write out every name.

df.names <- paste("Feteke", toupper(month.abb), sep = "")

# create a list of the data frames so that df.list[[1]] is FetekeJAN, etc.

df.list <- lapply(df.names, get)

# extract element 1, 2 of each, creating vector amazon.sum
