Error in y - predmat : non-numeric argument to binary operator - r

Trying to use R cv.glmnet() for cross validation on loans data.
I have a data set on loan data (Kaggle) and have already split into train, test.
Separated the y response from the predictive variables in select(1) and select(-1).
Created matrix so as to avoid the "Error in storage.mode(y) <- "double" : 'list' object cannot be coerced to type 'double' " problem earlier.
Now seeking to run cv.glmnet() for cross validation, but this error stops me now.
"Error in y - predmat : non-numeric argument to binary operator"
Error in non-numeric argument, yet all my data is numeric, save for one factor for response y.
As a side question, what is the predmat in "y - predmat" refer to?
x_vars <- as.matrix(data.sample.train.split %>% select(-1))
y_resp <- as.matrix(data.sample.train.split %>% select(1))
cv_output <- cv.glmnet(x_vars, y_resp, type.measure = "deviance", nfolds = 5)
cv_output <- cv.glmnet(x_vars, y_resp,
type.measure = "deviance",
lambda = NULL,
nfolds = 5)
I am also considering to try this function:
ddd.lasso <- cv.glmnet(x_vars, y_resp, alpha = 1, family = "binomial")
ddd.model <- glmnet(x_vars, y_resp, alpha = 1, family = "binomial", lambda = ddd.lasso$lambda.min)
Data sample is as follows, just some of the columns:
c("loan_amnt", "funded_amnt",
"funded_amnt_inv", "grade", "emp_length", "annual_inc", "dti",
"mths_since_last_delinq", "mths_since_last_record", "open_acc",
"pub_rec", "revol_bal", "revol_util", "total_acc", "out_prncp",

"total_rec_int", "total_rec_late_fee", "recoveries", "collection_recovery_fee",
"last_pymnt_amnt", "collections_12_mths_ex_med", "acc_now_delinq"
)))

Looks like a incorrect glmnet family, I accidently chose the default 'deviance' for cv.glmnet, when in fact my data was binomial. My next solution is to figure out "Convergence for 1th lambda value not reached after maxit=100000 iterations; solutions for larger lambdas returned"
Code that improved the solution:
cv.lasso <- cv.glmnet(x_vars, y_resp, alpha = 1, family = "binomial", nfolds = 5)
cv.model <- glmnet(x_vars, y_resp, alpha = 1, relax=TRUE, family="binomial", lambda=cv.lasso$lambda.min)

Problem with gam and mgcv packages: invalid type (list) for variable 'ti(LOC_X)'

I have the following data frame in R (heavily truncated, obviously):
X PLAYER_ID PLAYER_NAME LOC_X LOC_Y SHOT_MADE_FLAG
1 0 201935 James Harden 14 55 0
2 1 201935 James Harden 0 24 0

9 8 201935 James Harden -119 235 0
10 9 201935 James Harden -223 101 0
I named this data frame shots in R, and then tried the following:
league_model_19 <- gam(SHOT_MADE_FLAG ~ ti(LOC_X) +
ti(LOC_Y) +
ti(LOC_X, LOC_Y),
data = shots)
But this gives the error shown in the title:
Error in model.frame.default(formula = SHOT_MADE_FLAG ~ ti(LOC_X) + ti(LOC_Y) + : invalid type (list) for variable 'ti(LOC_X)'
I checked the type of each value in LOC_X, and all of them are integers. I understand the column itself is a list/series, but shouldn't this work anyways?
Any way to avoid getting an error here would be great. Thanks in advance.

So far I still can't replicate this. This should be a comment but is a bit too long.
Read in the data you've provided:
shots <- read.csv(text=
"X,PLAYER_ID,PLAYER_NAME,LOC_X,LOC_Y,SHOT_MADE_FLAG
0,201935,James Harden,14,55,0
1,201935,James Harden,0,24,0
2,201935,James Harden,50,74,0
3,201935,James Harden,160,215,0
4,201935,James Harden,22,21,1
5,201935,James Harden,-43,278,1
6,201935,James Harden,221,6,0
7,201935,James Harden,-27,21,0
8,201935,James Harden,-119,235,0
9,201935,James Harden,-223,101,0
")
The numeric variables here come out as numeric, but we'll convert to integer (to match your data as closely as possible) below.
Extend the data (randomly) to the size of your full data set:
sfun <- function(x) sample(x,replace=TRUE,size=1456)
set.seed(101)
shots2 <- with(shots,
data.frame(SHOT_MADE_FLAG=sfun(SHOT_MADE_FLAG),
LOC_X=as.integer(sfun(LOC_X)),
LOC_Y=as.integer(sfun(LOC_Y))))
Fit:
library(mgcv)
league_model_19 <- gam(SHOT_MADE_FLAG ~ ti(LOC_X) +
ti(LOC_Y) +
ti(LOC_X, LOC_Y),
data = shots2)
This works fine. You should try this code on your system and see if it works or not.
I also tried this with the data you provided above (333 rows) and it works fine.
So either (1) there's something weird about the remainder of your data that you haven't shown us, or (2) there's something weird about your R environment/package versions.
For (1), it would be helpful if you can post your full data set somewhere. (It should be sufficient to post shots[c('LOC_X','LOC_Y','SHOT_MADE_FLAG')], after checking that you still get the same issue with that subset of the data. We might not need all of the rows to reproduce, but we definitely need more than we have already.)
For (2), you could give us the results of sessionInfo() (or devtools::session_info()). It would be helpful to start from a clean R session to minimize the number of additional packages you have loaded, and to minimize the possibility that you have weird function definitions masking the ones in the package. (The results of find("ti"), find("gam") would also be useful; they should both be package:mgcv ...)

GBM Bernoulli returns no results with NaN

This data is not normalised, but it doesn't matter at this stage.
I can't get a simple gbm model work using the gbm package:
> require(gbm)
> gbm_model <- gbm(a ~ .
, data = train
, distribution="bernoulli"
, n.trees= 10
, shrinkage=0.001
, bag.fraction = 1
, train.fraction = 0.5
, n.minobsinnode = 3
, cv.folds = 0 # no cross-validation
, keep.data=TRUE
, verbose=TRUE
)

9 nan nan 0.0010 nan
10 nan nan 0.0010 nan
Columns 'e' and 'f' are factors. Train data sample size is approximately 6,000. I've tried running gbm with various bag.fraction, train.fraction, n.tree, and shrinkage values but still get the same result of all NaNs. Trees and SVM work without any problem on the same data. I even tried converting column 'f' to character, as it was suggested in previous posts, and it didn't work.
Edit: data has no NAs or invalid values. I tried one-hot encoding the 'f' column and still same results.
In my case, this issue was resolved by converting the dependent variable to character.
gbm_model <- gbm(as.character(a) ~ .
, data = train
, distribution="bernoulli"
, n.trees= 10
, shrinkage=0.001
, bag.fraction = 1
, train.fraction = 0.5
, n.minobsinnode = 3
, cv.folds = 0 # no cross-validation
, keep.data=TRUE
, verbose=TRUE
)

r2dtable contingency tables are too concentrated

I am using R's r2dtable function to generate contingency tables with given marginals. However, when inspecting the resulting tables values look somewhat too concentrated to the midpoints. Example:
set.seed(1)
matrices <- r2dtable(1e4, c(100, 100), c(100, 100))
vec.vals <- vapply(matrices, function(x) x[1, 1], numeric(1))
> table(vec.vals)

So the minimal upper left corner value is 36 and the max is 62 out of 10,000 simulations.
Is there a way to achieve somewhat less concentrated matrices?
You need to consider that it would be extremely unlikely that any given random draw would have a value with and upper left corner of 35. 1e4 attempts may not be sufficient to realize such an event. Look at the theoretic predictions (courtesy of P. Dalgaard on Rhelp list this morning.):
round(dhyper(0:100,100,100,100)*1e4)

If you increase the number of draws the probability of a single value of 1 "widens":
vec.vals <- vapply(matrices, function(x) x[1, 1], numeric(1)); table(vec.vals)
vec.vals

To get less concentrated matrices, you will have to find a balance between the number of columns / rows, totals and number of matrices. Consider the following sets:
m2rep <- r2dtable(1e4, rep(100,2), rep(100,2))
m2seq <- r2dtable(1e4, seq(50,100,50), seq(50,100,50))
which gives differences in number of unique value:
> length(unique(unlist(m2rep)))
[1] 29
> length(unique(unlist(m2seq)))
[1] 58
plotting this with:
par(mfrow = c(1,2))
plot(table(unlist(m2rep)))
plot(table(unlist(m2seq)))
gives:
Now consider:
m20rep <- r2dtable(1e4, rep(100,20), rep(100,20))
m20seq <- r2dtable(1e4, seq(50,1000,50), seq(50,1000,50))
which gives:
> length(unique(unlist(m20rep)))
[1] 20
> length(unique(unlist(m20seq)))
[1] 130
plotting this with:
par(mfrow = c(1,2))
plot(table(unlist(m20rep)))
plot(table(unlist(m20seq)))
gives:
As you can see, playing with the parameters helps.

Combine two data frames to put identical rows adjacent

I have to matrices (or data frames) that contain the same column and rownames.
The rownames of matrix 1 has an ID called dataTissue, the rownames of matrix 2 has the ID dataSerum. I would like to combine the two matrices where identical rows are placed adjacent (on top of each other). Please see my desired output.
I was thinking of using rbind, but I am not sure how to get this structure.

We can rbind both the matrices and then order by the rownames after removing the prefix part 'dataTissue./dataSerum.' from the row names using sub.

Error in doing factor analysis

I am doing factor analysis with 500 variables and 1316 records. I am getting the following error:
Error in solve.default(cv) :
system is computationally singular: reciprocal condition number = 2.5024e-18
The syntax I am using is:
factor.out1 <- factanal(covmat=cor(factor3, use="complete.obs"),factor=50,rotation="none")
Any suggestion will be of great help.
Thanks
