buscar y reemplazar tabs dentro de un archivo
Estimado Eric
Las filas que faltan, ¿son filas enteras, donde todo es valor NA o ?? en un data.frame?
Porque si es así podrías importar todo y luego buscar (filtrar) los que no son NA.
Copio y pego un código que utilizo en un trabajo, posiblemente le sea útil.
Tratamientos$Tratamiento[Tratamientos$Tratamiento == ""] <- NA # asignar NA a las celdas vacías

I made some progress on my previous "systemfit" question but still not quite there
Surprisingly, I played around with some test code and below actually
creates equations that look correct.
tempmat<-matrix(10,nrow=6,ncol=6)
restrictmat<-diag(6)
colnames(tempmat)<-c("AUD.l1","CHF.l1","CAD.l1","GBP.l1","EUR.l1","JPY.l

multivariate xts merge question
Hi,
I have an xts starting with a number of columns (currency pairs see below),
then I add new ones which are derived from existing ones (like adding the
moving average of a column) by merging the new columns one by one. These
get the name of the column they are calculated from concatenated with ".1".
All done by merge.xts, easy.
Now, I have a function (procState below) which generates

Media en subgrupos de grupos
Un saludo a todos.
Es posible que con el asunto no quede claro lo que quiero. Para eso añado una captura.
Dispongo de 3 variables (dos discretas y una continua) y me interesaría sacar la media tanto del grupo como de los subgrupos. Esta creo que es la segunda vez que escribo preguntando algo parecido. En la primera me hablasteis de tapply, pero con este comando sólo sé obtener la media de una de

Conditional subsetting
Hello-
Upon searching the email archives and reading documentation I haven't found
what I'm looking for. I have a dataset with a time/date stamp on a series
of geographic locations (lat/lon) associated with the movements of animals.
On some days there are numerous locations and some days there is only one
location. Associated with each location is an indication that the quality

Tilde en RStudio
Estimados miembros de la lista,
Cómo hago para trabajar con tildes en RStudio.
En concreto, cuando cargo un archivo .txt o .csv en RStudio, no me reconoce
el tilde com tal y me coloca otros caracteres en su lugar.
¿Existe alguna solución?
Saludos,
Manuel

zoo and coredata() classes
Hi guys
I have a reasonably basic question with zoo usage, but I havent been able
to find a satisfactory workaround yet.
Heres a simple example of what I'm talking about (the following data frame

How to deal with a dataframe within a dataframe?
Hello all,
I am doing an aggregation where the aggregating function returns not a
single numeric value but a vector of two elements using return(c(val1,
val2)). I don't know how to access the individual columns of that
vector in the resulting dataframe though. How is this done correctly?
Thanks, robert

Calculating First Occurance by a factor
I'm having difficulty finding a solution to my problem that without using a
for loop. For the amount of data I (will) have, the for loop will probably
be too slow. I tried searching around before posting and couldn't find
anything, hopefully it's not embarrassingly easy.

perl expression question
I have a string such as
fileName<-"Agg.20.20.20-all-01".
All I want to do is pull the "20.20.20" and the "all" as strings.
Obviously, they aren't always those values.
The "20.20.20" can be "30.30.30" but it's always after the . which is
next to the second g in Agg and it's always the same length. The all

[LLVMdev] GEP::getIndexValid() with other iterators
Hi all,
currently, GetElementPtrInst has a method getIndexedType, which has a
templated variant. You pass in a begin and an end iterator, and it will find
the indexed type for those. However, both iterators must iterate over Value*.
For some argpromotion code, I would like to pass in iterators that iterate
over unsigneds instead of Value*. I currently solve this by transforming my

[LLVMdev] A potential bug
Hi all,
There might be a bug in DeadStoreElimination.cpp. This pass eliminates
stores backwards aggressively in an end BB. It does not check dependencies
on stores in an end BB though. For example, in this code snippet:
...
1. %sum.safe_r47.pre-phi = phi i64* [ %sum.safe_r47.pre,
%entry.for.end_crit_edge ], [ %sum.safe_r42, %for.body ]
2. %call9 = call i32 @gettimeofday(%struct.timeval* %end,

transforming factor back to numbers
Hi
I generate a new dataframe by doing:
npl.agg <- aggregate(npl$DensPlants, list(year=npl$year, sim=npl$sim),
mean, na.rm=TRUE )
Now I want to plot it by using
coplot(npl.agg$x ~ npl.agg$year | npl.agg$sim, type="l")
but, as npl.agg$year is seen as a factor, the order of the points on the
x-axis (time axis) does not follow the numerical sorting 1...100, but

creating chron object aggregates (e.g. sums by day)
What is the recommended/optimal way to perform aggregates on data frames
with chron objects?
Here is an example:

6 07/16/01 600
7 07/17/01 500

Apologies for the previous mail (I sent it off too early by mistake).
This is the correct example:
