See what this gives you: names(Mytsdata) That's because a ts object doesn't use names. This is usefule beyond str() to see what the object looks like. dput(Mytsdata) What were you trying to do here: names(Mytsdata)<-c("m","sp") > head(Mytsdata) the last command shows nothing changed.

> Mytsdata<-ts(mydata,frequency=12,c(2014,12)) does not. So for my data I have to use the above formulation. This is because you passed the whole dataframe into the data argument, and usually you likely only want to pass a vector from the data frame. > Why are there two sets of [] around...

mydata[['Spend']] This is grabbing the Spend column using column indexing. Almost identical to mydata[, 2] but safer in that it's gauranteed to return the vector not a list. Error in C(2014, 12) : object not interpretable as a factor R is case sensitive C is not c

It does but it's subtly using indexing as in [, 2] So this will likely work: ts(mydata[['Spend']],frequency=12) But you need to specify start = c(YOUR_START_YEAR, YOUR_START_MONTH) The dollar signs in the head you show above indicate character. R stores numeric/floats without dollar signs.

usnim_2002[, 2] Above you grabed 1 column, a vector. Do the same for this new data set with Spend start = c(2002, 1) Above you specified a date start (year, month) but don't this time. Also I think your data is character. Maybe use lapply(mydata, class) to see.

> stringsAsFactors=T had to go at some point! Agreed, but there was some pain (though minimal)

It's hard to help because we don't have the data. If you can make a minimal working example you're sure to get a quicker response.

I like dplyr and tidyr for analysis...for programming they're a *****...mostly because the API is constantly changing. You can't make data science pipelines with an unstable API.

Look at the check.names argument?

I take it back PSPP is the way forward: https://www.gnu.org/software/pspp/

There was a crappy open source version of spss I tried once upon a time before R...pspp

I'm sorry hlsmith but it's still not clear to me what you want. Can you draw the image by hand, take a pic of what you'd expect it to do? Also why plot x on the y axis and y on the x axis Or just poor variable names?

TIL about the strtrim function...used to use substring(1, n)...not a huge savings but cool and semantically easier to think about: x <- 'Dason is a horrid human being (or bot) devoid of any type of empathy for others. He has amassed his fortune at the expense of all that is holy and sacred...

I agree with Dason on all points.

In R (via stringi) I could write (?<=a|bc) but doing this with the re module results in this error: raise error("look-behind requires fixed-width pattern") error: look-behind requires fixed-width pattern Is it true that if I have the regex (?<=a|bc) in Python I need to write it as...
