Resultado operación entre dataframes
Buen día estimados,
Tengo el siguiente código:
df_1 <- data.frame(ana = c(15, 20, 30), maria = c(15,20,30), jose = c(15,
20, 30))
df_2 <- data.frame(nombre = c("jose", "ana", "maria"), valor = c(1,2,3))
# Find the corresponding columns in df_1 based on the values in df_2$nombre
cols <- match(df_2$nombre, name...

Suppress legend in plotting groupedData
...tell how can I suppress the legend (automatically created) when I plot a groupedData.
suppose that I have data farme df_0 which contains the following columns: ID represents the clusters, t represents time of observation, Y: the variable of interest and X a binary covariate. Then:
df_1 <- groupedData(Y ~ t | ID)
plot(df_1, outer ~X)
This gives me the plot (Y ~ t) for each cluster with a legend containing all the clusters.
How can I drop the legend?
Thanks you very much,
Bernard,

Looping through names of both dataframes and column-names
...s())]for (df in nls) {
print(df)
for (var in names(get(df))) {
print(var)
assign(paste0(df,"$",paste0(var,"_cs")),cumsum(get(df)[[var]]))
}}
ls()[grep("df_",ls())]
The code above *almost* works, except that it creates a whole bunch of
objects of the form df_1$x_cs,df_1$yx_cs ..... What I want is 5 dataframes,
with the $ elements enclosed, as usual.
Any help or guidance would be appreciated.
Much thanks,
Dan

data frame names in sequence
I've been stuck with this problem for a whole afternoon. It's silly but
totally pissed me off. I have a set of data frames with names in a sequence:
df_1, df_2, df_3, ..., df_20. Now I want to access each data frame (read or
write) in a for loop, in a way something like this:
for (i in 1:20) {
df_i <- ######
length(which(df_i[,7]==1))
######
}
I tried paste or cat ("df_", i, sep=""). But neither way works. Your help is...
